> The ability to opt-out of quote posts is also currently planned, which makes it that Mastodon’s implementation will not be compatible with other fediverse implementations of quote posting.

Not surprising. Even before ActivityPub was announced, when the #fediverse was still powered by #OStatus, Mastodon was already breaking compatibility. There were countless of heated debates about almost every Mastodon-only "feature" they implemented that all other Fediverse devs were _forced_ to implement.

And here we are with yet another.

I wonder what will supporters of opt-out or anti-quotepost camp will do if the other Fediverse devs ignore this Mastodon-only "feature", and just continue with the common implementation of quote posts? Are we going to see a new reason for "fediblock", and finally fragment the Fediverse network?
