A bunch of Firefox and Chromium derivatives are not a long term solution. The good news is that both Chromium and Firefox are open source. The bad news is that Google is funding these (and Safari too) via advertisement revenue. So, Google holds a lot of power here. And absolute power corrupts absolutely. The core of the issue is that Google pays directly or indirectly for the salaries of most of those working on Chrome/Chromium, Firefox, and Safari. Their money is funding the whole thing. Alternatives like Ladybird that lack this funding and commercial backing don't stand much of a chance to catch up technically. Unless they nail a sustainable funding model that isn't Google bribing them into submission. Both Chromium and Firefox are fixable and there's plenty left to salvage. Firefox has loads of regular contributors. Mozilla employs many of them of course but not all. Aside from the drama at Mozilla, it's a pretty well run and healthy open source project. Same with Chromium probably. Though most developers are likely Google employed currently. The solution isn't moving the problem to some new project but actually addressing the core issue. Which would be funding them properly.
