It gets my goat that people think it’s a good option. There are plenty of articles explaining some of the many issues with it, but a few are:
- It’s run by anti-LGBTQ+ crypto bros.
- It has ads right out of the box.
- It collected donations towards people who never signed up for them - then held them to ransom in exchange for the kind of information you should never share on the Internet.
- They’re a for-profit advertising company. “Privacy-centric” my elbow.
You (the end user) decide how you want to use the internet. The forks you’re probably angry about are the ‘hardened forks’, but whether or not you care about their goals and want to use those is a choice only you can make. Most of what they do is basically change some default configs and remove some ‘bad’(according to the maintainers and the users) features.
There’s also forks like zen that under the hood use firefox, but customize the user experience significantly.
Long way to say what is captured in two words: opinionated firefox.
