Idk why nobody knew about it until recently, ime (and I’ve never used Zorin), I feel like even before the recent (likely paid advertising) campaign I still saw it almost once or twice per thread, usually something like “I’d go mint, unless you need cutting edge then Fedora, or if you really need it to look like windows then there is Zorin,” some saying “I haven’t used it but I hear it’s windows like” and stuff. I’ve seen stuff like that consistently for the last 4 or 5 years since I switched and I was the one asking distro advice and being told mint, fedora, zorin, or pop. It has never been the top answer but it was always there, lurking in the shadows.
