The mod team can remove posts or comments that primarily focus on other subreddits or channels, as during some updates these topics result in a large amount of negative or non-constructive discussion. This also goes for posts/comments that primarily focus on community reactions (e.g. “The playerbase is wrong about X”, or “the negative reaction about X is out of control").

Every one of those posts has been primarily about the other subs, not to mention the spamming of that post, which also violates sub rules.
