This is kind of long and please spare judgement to a certain degree, I'm just a small youtuber trying to offer one bit of perspective on "clickbait". And I'm not defending or condoning any other actions of other youtubers, and it totally sucks that you had this happen to you. I'd be mad about that too.
As a content creator, the problem with the clickbait titles is the fact that a creator will often times never get noticed unless they use them from time to time and that's partially because everyone else uses these stupid clickbait titles to promote their stuff too. Even if the video is fundamentally the same as someone else's. Who cares whose is better or whose was there first, the clickbait title often times wins. The only people who get away with not using them every once in a while are people who are already established on YouTube, or they're datto.
We love datto because he was an early Destiny PvE guru and he does his research, he's also well spoken and not obnoxious. Datto would get more views and more subs with clickbait titles. Does he do that and pursue that route? No, because datto doesn't need to. He probably isn't trying to game the system and wants his videos to feel important.
But, here's my example (mind you, I'm the tiniest Destiny based youtuber ever and I don't make money off of my videos anymore because I just hate ads so much):
I uploaded a video fairly early on in taken King about the eyasluna and what a good roll would be, this was before most people had even said anything about how good it was. I titled it something like "Eyasluna review and good rolls to look out for". Simple title, straight to the point, not a terribly edited video imo, etc. It got 50 views in like a week and I have 1600 subscribers. So I said meh. Failed video. Okay. Try again later.
On the way I noticed destiny youtubers using titles like "OMG BEST DESTINY PULSE RIFLE" and stuff like that. I thought, "hmm...clickbaitey. But I really want to know what pulse he thinks is the best so I can converse with him about my opinion about it too."
So I uploaded another video within a month or two of that other video and deleted the other video, this time it was a video on another eyasluna I got that was very well rolled (true sight, rifled barrel, rangefinder, luck in the chamber). Learning from the previous example and the other youtubers, I titled it "EYASLUNA GOD ROLL, SUPER OP". Obnoxious, right? Well I got 500 views in three days, which was awesome for my teeny tiny channel. Then I retitled it to "Eyasluna god roll" and now it's still sitting at around 600 views. The CAPS and stupid titling drew people in and they were conversing with me asking if they had a God roll/what they thought a god roll was.
Another time that happened was when I uploaded a PDX-45 video that got 17,000 views, because I had titled it "BEST PULSE RIFLE IN DESTINY", literally copying the title from that youtuber from earlier.
TLDR: Clickbait sucks so bad, but I'm gonna get 1/5 of the views someone else would on the same topic because of their clickbait title and my non-clickbait title. And I can live with that, but a lot of creators want their chance to be noticed.
