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."
I'm trying to figure out if there's content there you can't access via Mastodon or what's the catch. They say it's not ActvityPub compatible yet however it's still somehow up so what's going on.
looking at the app it seems it's launched with just local content feed with a promise of being mastodon compatible in the future. I guess specifically to generate some unqiue content so people join.
Threads automatically adds all your instagram follows so for creators they don't have to try and rebuild their audience on a new platform where as for users they don't have to find all their friends/family/and creators on a new platform, its just there. There is also the ease of signup, if you have an instagram account you just log in, if you don't it's really simple. For Mastodon there's different servers to pick and then you have to find your favorite creators again and it's another login to remember.
TLDR people are lazy so go with the option that is easiest for them
