There's nothing removed though? I'm seeing the post and all comments. And it's a low effort meme in a subreddit for discussions on how to buy local instead of US products, so I'd agree with a mod if they did remove it.
You picked and chose the reason that made you angry, but they also mention repeated posts, which is probably the reason why it got removed if there are other posts about Lemmy...
But it didn't get removed, did it? It's just a mod comment that's there are a warning.
It's also just a meme and not something that actively contributes to the movement.
Platforms should not carry advertise for their competitors so this is fair. This should be an official policy though, not a random removal.
I don't understand why restaurants allow ads for competing restaurants while I'm eating. (they probably don't have a choice, but if I was an owner that would be a reason to remove the screens) Transit operators should not have ads for cars. reddit should not have ads for lemmy.
