It’s in German…
Firefox has a fully local translation service built in these days that works quite well with German.
On iOS at least, you can just tap the translate button.
The article is basically just a long unsubstantiated rant though.
That article seems incredible naive when it comes to Threads and ActivityPub.
I think it is better to hear what Zuckerberg himself has in mind, as outlined in this more recent article (based on a interview with him): https://fediversereport.com/zuckerberg-on-threads-and-activitypub/
I don’t think its naiv. I think its more realistic. I like most about the article that it puts the activitypub-protocol front and center. This is mainly what made me view the fediverse differently. And that therefore power dynamics will probably shift in the next years away from Mastodon.
