My wife is looking forward to deleting her Instagram account once she can connect with the same folks from her Mastodon account. Being able to remain in touch with over 100M people who still use Meta products out of the comfort of an ad-free, privacy-friendly platform like Mastodon is a game changer.
I hope that an organization as massive as Meta adopting #ActivityPub will send a signal that pushes Tumblr and other platforms that have been considering it over the edge in doing the same. Perhaps even Bluesky would consider replacing or at least supplementing their custom protocol with the @w3c standard for interoperability.
@Gargron Why a company such as Meta (or whatever) would want that interoperability, when they don't necessarily need it? That is a serious question yet to be answered. I'm not against any adaptation in the first place btw.
