I have webrtc completely disabled in browsers.

I tell everyone, and I abide by : never use an app if you can use the website. If they only have an app be prepared to be fucked.

I also use a VPN / firewall / DNS filter (by domain and by IP). Rethink or invizible provide all 3 in 1 on android. On linux rotating VPNs, rotating local DNS resolvers [dnscrypt-proxy with local doh with blacklists], and strict firewall rules.

*Facebook* , *meta*, *Instagram* etc are blocked in and out. As are Google "safety" domains, and a lot of their APIs.

Privacy may be inconvenient, but selling (giving away for likes) your soul to the devil could cost you a lot more.
