Im fine with reposts, even reposts without credit. But reposting a meme from one lemmy community to another lemmy community a day after the original and not crediting/cross-posting is just shitty and pointless. Sharing a meme to another platform is the digital version of telling a joke, sharing it to the same platform is the digital version of saying someone else’s joke louder.
They’ve also been pretty open about doing it to take traffic away from ML, which is a noble thing to do in my opinion.
