I don't really agree. Topics are materially different from FLoC. Especially in the way of moving it from a shady background activity into something the user can interact with.

Also, nobody really gives a shit about it. WEI could break adblockers and that would be a huge issue.

Eternal vigilance is the price of liberty.

I just got a topics intro popup on my work computer the other day. One of many many other reasons I'm happy I use Firefox at home.
