Red Hat were interested. They funded desktop Linux heavily for a long time. It didn't work because the (non-capitalist!) ideology of Linux is incompatible with success, and Red Hat always tied down by the community they chained themselves to. Desktop platforms have far more hardware and software heterogeneity than server platforms do, the pace of innovation is much faster, and they require the ability to ship closed source software, closed source drivers, to innovate and then for people to capture some of the value to fund all that.

For the longest time desktop Linux simply tried to clone Windows/macOS. Eventually Red Hat came to dominate GNOME enough that it developed a bit of its own personality, but the kernel and software distribution approach always held it back from even matching its competitors in usability, which wasn't even close to enough. Apple have executed excellently for decades and even they only made progress in the pure consumer space, the enterprise space is one they never tried to attack despite having the money needed to do so.

Capitalism isn't the problem here. Communist software isn't exactly famous for being impenetrable, in fact it's more famous for hardly existing at all. Google and Apple are highly capitalist, and their security stance is much better. The problems at MS are deeper.
