They should have been competing with Citrix and others in the B2B space rather than in the B2C space with MacBook users. I am not sure why they didn't, even with something like Citrix they could outcompete it on UX alone, like Zoom did with Webex, ie lower latency, it "just works" etc.
Probably due to time constraints. B2B takes a long time to get moving, B2C allows fast feedback for rapid iteration early on. B2B requires integrations, lots of tangential work that doesn't build the core product.
They may actually have made the right decision - it got them to "time to pivot" without running out of cash.
