I see your points, but in many ways this isn't up for either you or me to decide. In general someone else doing something illegal does not give you the right to do something illegal yourself. You can sue them, but you are not allowed to break the law or a license to get what you consider to be justice.

And as a moderator it is not up to me to decide if this is justified or not. Moderators are supposed to make sure that their subreddits follow the reddiquette, and the reddiquette clearly forbids any illegal activity. Sharing unlicensed APKs is not covered by the license, so we delete all of them. This is completely independent of the reasoning, we e.g. remove links to free APKs that are regional locked, like those available only in the US, where the reason why they aren't available elsewhere isn't money, but only some weird legal construct or someone simply forgetting to enable it world wide. It is very important for the mods to stay sort of neutral, so if there is a rule, it is not up to the mods to decide whether it applies or not, they just have to enforce it in the same way for everybody. We don't delete posts lightly, and because we try to explain why we have to do it, this takes a lot of time which is basically wasted for us.

There are gray areas, e.g. at which point does a developer posting about his own VR app cross the border to spamming. We usually check what the submitter posted before, if the majority of the posts are just links to the Play store etc., all this is very time consuming, just to make sure we delete only posts which break the rules on reddit or /r/GoogleCardboard. But for redistributing APKs it is very simple: to downloaded them from the Play store, you had to agreed to the Play store EULA, so you entered into a legal agreement with Google. You are under no circumstances allowed to redistribute them. FIBRUM themselves wouldn't be able to allow you to redistribute the APK from the Play store, they would have to provide it to you by another way. The EULA breach is completely independent of any shit that FIBRUM pulled, it involves Google and Play store users. So while the policy on what is spam and what not is the result of a discussion, partly public, partly between the mods of /r/GoogleCardboard, the APK request were removed due to requirements stated by reddit itself, which is why there won't be a discussion. The jobs of moderators is to make sure the reddiquette is followed, not ignore it themselves whenever they like. If it is illegal, it is not allowed on reddit.

Of course deleting the posts won't solve the situation, but not deleting them won't solve anything either and isn't even an option. But it doesn't prevent looking for solutions. We only delete requests for APKs and links to APKs, but never comments or posts that discuss the situation. We don't remove links to sites that allow downloading APKs from the Play store in different countries either (but direct links to APKs on these sites will be deleted), or descriptions on how to use them. You are free to discuss solutions, hint at options, explain how to work around it. The only thing you are not allowed to do is use reddit for directly sharing unlicensed software. Basically it is up to you if you want to breach the license or do something illegal, you are free to discuss this, but you mustn't use reddit for the actual act. And there are tons of sites that allow this, so at best this makes it a little less convenient.

I also doubt that what FIBRUM does would even qualify as illegal. They try to trick you into starting their process by hiding the fact that they'll ask for money later, basically hoping that you will still pay, because you already gave them the data. I haven't seen the mails, so I cannot really tell how bad the trickery is, but similar to companies that send you bills suggesting that it is for something you ordered, this itself isn't illegal, just very bad business conduct. You still get to decide if you pay or not in the end. Trying to fool you into believing that you'd get the app for free for giving your data makes FIBRUM a bunch of assholes, but that's about it. Being an asshole isn't illegal, pretty much the only thing you can do is avoid assholes and warn others about them.

Depending on where you live, courts decide differently how obvious the company has to make the final price in the initial order, but at best you can demand your money back or demand a reduction in price if something was added in the last steps of the order. But if you haven't payed any money, you probably didn't enter a license agreement, so legally you aren't entitled to use their software. Whether all this is morally acceptable is a completely different question. The only actual solution would be FIBRUM changing their behavior again, and this would be best achieved if people didn't give into their demands. If they download numbers drop to zero because nobody talks about them anymore, they will probably rethink it. This of course is inconvenient again, as it means not having access to the software.

There is a gigantic discussion about the ethics of stealing software, who gains and who loses, but e.g. one of the major reasons why companies play a shitload of money for Microsoft Office is that this is the only Office package that most people know. And most know it not because they payed for a license themselves, but because someone installed an unlicensed copy on their computer, even though free alternatives were available. It would be a lot better for the software market if people actually bothered to look for alternatives instead of simply using cracked software because it is more convenient, as this would entice other developers to create software.

FIBRUM made nice demos, even though they are mostly all only rides and don't offer a lot of replay value. Their apps showed up in pretty much every "what should I install" post on /r/GoogleCardboard, so if we collectively decide to no longer promote them and look for alternatives instead, this would actually be a solution that in the long term benefits everybody except FIBRUM.
