Elon's take over of Twitter has set a lot of things into motion in the digital world 
Tumblr and now also Flickr are thinking about intergrating ActivityPub so it will be able to connect to the Fediverse! 
A lot of lay offs in the mainstream social media but the Fediverse is only growing!
The world is waking up 
Social media can be fun but also privacy friendly at the same time, you got the proof now!❤️
No billioaires needed ✅
@stux inb4 one of them pulls the rug on #ActivityPub to replace it with a new, proprietary, protocol that they control because it's "better" and "supports their platform better". "Hey folks! #Tumblr is phasing out ActivityPub but register your instance for an API key here to integrate with us using our new protocol, [TumblPub?idk/c]".
Would it destroy #mastodon ? No. But it would put a significant divide in people coming from #TwitterMigration who would then funnel off to tumblr in the end.
@stux Why else would #tumblr be so quick to jump on the #ActivityPub bandwagon? How many platforms integrate with other, competing, platforms? If they jump in now, they will catch so much more of the crowd flocking from #twitter than #mastodon simply because of their existing reputation & status in social media. Then they can just pull out of the federation whenever they see fit.
@Rob
The current owners of Tumblr (Automattic) have also enabled ActivityPub support for WordPress. While it's possible that they might do such a thing as you describe, such an action would *very significantly* hurt the brand image they have cultivated, and unlike Twitter they are not run by an incompetent nitwit.
Plus, if more social media companies beside Tumblr join in, any one of them doing that would become harder to pull off.
@stux
@mathlover @stux I'm fairly certain there must be similar discussion. I've seen quite a bit about whether brands should have accounts here. omg could you imagine... talking to your #instagram friend through #tumblr in a group dm with a buddy on #flickr? This seems pretty weird..
@mathlover @stux I just want to note that I do notice some slight attention deficiency in that toot.... notably the big shift in topic halfway through.
@mathlover @stux well, let's think more generalized. I used #tumblr as more, an example, of what could happen of ANY corp getting involved. But I do think that #Automattic is a good one that would not intentionally exploit or cause harm to the community.. but how many out there would? What can the community do as a whole to discourage it & make it not worth their while?
