I use Firefox and Safari. And I’m intrigued by Brave. I only use Chrome when compelled to. Google and other companies like Facebook have overreached in abuse of users privacy. And Chrome is a resource hog.
Zoom? I use it when compelled. Jitsi — which is free open sourced and DOESN’T sell your data — is my choice.
I quit both Facebook and Twitter last year.
You can’t replace the most aggressive and greedy companies all the time — what’s the replacement for YouTube ?— but in many cases you can have a better experience for free. I recommend it.
