Disagreed, at least on Mac, while there are (free) apps like Fork.
I bought a license a while back, since I use it every day. That said, I believe they're moving towards a "trial" model, rather than "free" as in beer.
I do wish it was open sourced, but also wish them the best in making it a profitable venture. It's great software, it deserves good funding so the creators and users can benefit from it.
I'd recommend giving it a trial run. For me it ticks all boxes for personal and professional use, I'm very happy with it. The managing of a large number of repos could be better, but I do OK with a single "hub" folder to keep all repos, with nested folders and symlinks.
I haven't tried Fork. For my side projects I don't need to merge or anything often, and when I do I use Idea's three way merge tool anyway.
