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)
I think it just feels more comfortable and “professional” also. I’ve talked with people for whom the jank associated with decentralized services is a total deal-breaker. They started a Mastodon account, but they picked the wrong instance and it got defederated because it had Nazis, they got annoyed and moved to a different instance, and then a few months later the admin for that instance evaporated without warning and rather than find a third one they turned their back on the whole endeavor as a hopeless kids-lemonade-stand waste of time.
Yeah most people after two bad experiences will just leave.
