Especially when they promote and use it out of “moral motivation” to “fight against twitter/big tech”. You’re still using a platform owned by one company. They’re not really decentralized. There’s nothing stopping them to go down the same path twitter did. They’re funded by some questionable investors… Or, to quote something I recently read: “BlueSky is decentralized in the same way Total Energies is a green company.”

Fight big tech, yes, but know which platforms to use. And to counter all “but Mastodon etc. are boring”: the more people making the shift to the fediverse, the less boring it gets.

Edit to add: “shame” might be a heavy choice of words, but I don’t know another term haha (English not a first language and all that)
