Many of us do not trust Facebook and anything it is associated with or swallows up.
EDIT:
"Instagram head Adam Mosseri said "
““Soon, you’ll be able to follow and interact with people on other fediverse platforms, such as Mastodon. They can also find people on Threads using full usernames, such as @[email protected].””
“We’re committed to building support for ActivityPub, the protocol behind Mastodon, into this app. We weren’t able to finish it for launch given a number of complications that come along with a decentralized network, but it’s coming,” he said.
“If you’re wondering why this matters, here’s a reason: you may one day end up leaving Threads, or, hopefully not, end up de-platformed. If that ever happens, you should be able to take your audience with you to another server. Being open can enable that.”
“centralized” and “decentralized” are a spectrum, not absolutes. Mastodon might be decentralized in theory but if everyone uses a single instance then it’s centralized in practice. That isn’t the case right now, but it’s also not entirely not the case, either. Same is true for lemmy
This perspective would also make the conversation surrounding it pointless. The proposed idiosyncrasies you suggest don’t change the overall discussion in this thread. It’s a non-actionable perspective. It’s like saying no one can know anything ever. It’s technically philosophically a valid point, but it serves no purpose and doesn’t help in most conversations.
