looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don't run a complaint browser ( cough...firefox )
here is an article in hacker news since i'm sure they can explain this to you better than i.
and also some github docs
Well, I've made the point yesterday that it's unfair if another person expects me to always use what's convenient for them, but never returns the favor. And that there's no desktop client for WhatsApp for Linux, and that my wrists are bad with touchscreens, and that Meta are bad guys.
It was unexpected, but this worked and I now have some XMPP contacts, relatives, of course, who else would listen to me on that.
I had no problem convincing relatives to use Signal, I am still required to have WhatsApp because every workplace requires it.
Same, but the trick is to force workplace to pay it and deal with it. During the three years I was freelancing I had four company phones at home and had to pay for none of them, other than battery rechargings (and that's when I ever brought them home; on weekends I just powered them off and left them in the garage).
