“We” didn’t stop using Firefox. Open source boycotts are complicated because the software is separate from the developers. You can keep using the software even if you disagree with the development organisation.
Mozilla organisation is getting problematic for a whole lot of reasons. My issue with them is that they seem to be in the “more money than they know what to do with it” phase. They’re flush with cash, but it’s not reflecting to the product. If they buy an ad company and plan AI stuff, maybe things aren’t going well.
Problem is, there’s no viable competing organisation. Protest forks of software don’t really work that well unless you can actually guarantee the development support. Compare this to what happened when OpenOfficeOrg successfully moved to LibreOffice - developers saw the old organisation didn’t work, so they made a new one that did.
Debian girl here. We may not have updated anything in 5 years but boy howdy are things stable or what.
