You didn’t just say that. You said a whole lot of other things. You lead with the fact that it’s well known within the industry. The implication of your comment is that the companies did nothing wrong, and people are idiots for not knowing this stuff before. If that’s not your stance, you should make your stance more clear.

If you instead simply said “people should also be angry at all these other extensions and companies, they’re complicit and just as bad” then nobody would be calling you out for astroturfing.
