In the few short hours since I started using #Threads, #DuckDuckGo has already blocked over 200 data tracking attempts. These include things like "headphone status" and "screen density."
The only way I'll use Facebook nowadays is in a browser sandbox. And before you ask, it's pretty much Events and Marketplace nowadays; the main feed is unusable and horrifying nowadays, and everybody I know has moved on from Messenger.
Hermit browser does a good job of sandboxing random apps like that. Wish it had more than 5 sandboxes though, it severely limits its usability.
Everyone I know pretty much uses fb messenger exclusively, it's the only reason I still have it. If there was a reliable way to hook into messenger from another app I'd switch in a second, but still the reliance on messenger is there.
