I can understand firefox after mozilla changed faces & be came greedy data aggregators but the browser wasn't bad which I was appreciative at first. But then google had to come out with chromium & make that apart of web pages & applications so now lots of sites certain functions don't work properly. Forcing you to hey let me just use google chrome or a partners with google browser like brave or make it more inconvenient to try to stick to something more securely friendly by having functions break.
I get how your feeling with being drainrd by telemetry, data aggregation, & invasion of privacy when accepting tos & pp just to use a service. Thats the type of mindset they want everyone in so nobody makes an effort anymore they want your effort to feel hard & meaningless while they try to roadblock & cut off every possibility to live a private life. It's easy for them to do these things & they don't care because they know the common people will never be motivated enough to unite & do something about it.
No ceo is ever gunna wake up to a protest outside his house over a data aggregation collection technique being considered wrong & immoral. They trained the world years ago to be stuck in the cycle of work, eat, relax, sleep & anything else is stress. Positive vibes only because negative will destroy your eco & round around & round again we go anything else ain't nobody got time for dat, you got a problem post it on social.
Posts on social who gives a shit. That's why I think it's important to never give up, have hope, & seek knowledge in alternatives. Convenience does not require sacrifice or compromise. I would keep searching but if you stick with vivaldi I would search to see if their are ways to fully remove the telemetry collection. I know they had sidebar tabbing which was cool but I could find an extension to do that as well.
