The mass exodus from the Facebook platform has already happened. The others are in progress.

It’s already happened to Facebook. And it’s happening to Twitter. And Reddit. This stuff takes time, but the character and feel of each service has shifted considerably.

Enshittification isn’t always driven by a conscious person or organization with an agenda, much less one with an agenda of short term financial gain. Sometimes the aggregation of a bunch of individual decisions causes something to get shittier. Or better. Or just different. 4chan is not at all like it was 20 years ago, but it wasn’t because of corporate influence. The culture just changes.

So if the question is whether the fediverse might someday suck, I think the answer is probably yes. It remains to be seen how it will suck, who will have caused it to be that way, and whether there will be other nice things about it.

And that introduces a specific type of supply chain threat: someone who possesses a computer can infect their own computer, sell it or transfer it to the target, and then use the embedded microcode against the target, even if the target completely reformats and reinstalls a new OS from scratch.

That’s not going to affect most people, but for certain types of high value targets they now need to make sure that the hardware they buy hasn’t already been infected in the supply chain.
