Apart from everything else that has been mentioned I would add that a very real factor is that every instance to my knowledge has a donation button which cannot be removed without forking the project that goes directly to the devs. Plenty of people in this post are saying things like "Wow, glad they cleared that up! I'll definitely be giving them money" and very likely don't have the full context. Assuming Lemmy does continue to grow exponentially it wouldn't be unreasonable to assume that these devs will probably receive a large amount of money in donations from people who may not all be okay with supporting them if they were more informed. So spreading the truth about the devs and not taking their pitiful denial as absolute truth is important even if you believe in the project as a whole.
