Are they disconnected from its customers in current year?
They may be alienating the core audience that made them who they are, but I don't think they're disconnected from their customer base, which has changed. RTSes are not popular and they are not platform-agnostic like an FPS is.
The UBO on Safari has the same issue as chrome except that it has been that way for several years longer. They brought back the lite form of UBO only recently as, presumably, the developer saw the writing on the wall and mv3 and Safari carry the same limitations.
I think safari is largely fine but there are a lot of web APIs that it doesn’t support, rightly or not. A lot of devices are configurable through serial connections using the Web Serial APO thats only available in chromium browsers.
As a primary browser it really comes down to ergonomics. Things on top of the engine that make someone prefer one browser over the other.
