Mastodon the non-profit is all but compromised.

The guy in charge is essentially in cahoots with Meta and is under an NDA from them.

It doesn’t take more than 2 seconds of thinking to see how empty the words are that Mastodon is not at risk.

1. Threads federates with Mastodon instances
2. Threads uses its massive engineering resources to implement proprietary functionality that’s incompatible with Mastodon instances
3. A non-trivial number of Mastodon users jump over to Threads, this is the first wave of people that leave Mastodon
4. Threads drops support for federation and silos itself off
5. The majority of the remainder of people on Mastodon jump over to Threads because they want to be able to continue to interact with the people that jumped over to Threads and/or because they want to be able to continue to interact with normies now that they’re used to that
6. Mastodon is effectively dead, safe for a select few that stick to their guns

3 and 5 will happen in a cascading manner, the more people switch to Threads, the more others will also want to switch.
