"Mozilla can end anyone's access to Firefox at any time for any reason" How. The program is open source. Anyone can remove/disable telemetry or other access

"Mozilla can end anyone's access to Firefox at any time for any reason" How. The program is open source. Anyone can remove/disable telemetry or other access to Mozilla servers before compiling. Alternatively, using other open source software, anyone can prevent Firefox from accessing Mozilla servers. I stopped relying on graphical browsers for recreational web use starting back in 2000s. "Mozilla owns royalty-free, unrestricted access to your inputs processed by Firefox (like Search, Web History, etc.)" But the Mozilla press releases and blog posts about protecting user privacy will continue. Mozilla should be sued for all their misrepresentations. Through discovery the public may learn what this company is actually up to.
