It's really not an exposé against MS. He calls himself a die-hard Sony fan, so it's obviously just a fan/dev with a personal preference. I think he just provides some obvious confirmations on things we already knew:

• A game can be made on a supercomputer and still struggle at 1080p, simply through some bad coding. Pretty sure we all knew this already.
• Both consoles have great hardware, and both will be fine with 4K.
• Sony seems very supportive of their devs. We've heard this many times before.
• The technology won't always make a better game; It's the developer's ability to utilise it.
• Both systems have SSDs that will provide game-changing abilities.
• We shouldn't get too caught up on the specifics and technical differences between the consoles.
• Sony has a lot of great exclusive content compared to MS. Unfortunately, I'm sure we all know this.

He's not exactly talking "shit" and "bullshit" that we shouldn't believe haha. If no one talks about this interview, well... that's probably because it's not actually providing anything interesting that we don't already know. It's a small channel that would only be able to get a small, not well-known dev on to chat, which is what he is.
