Which is why Microsoft had to use such dirty tricks to prevent them from making inroads into workstations and desktops at the point that they still had competitive hardware.

Sun was a hardware company that did everything it could to commoditize software. That strategy works extremely well for hardware companies -- Intel successfully did the same thing for many years -- as long as their hardware is competitive.
They were perfectly content to sell SPARC hardware with Linux on it. But to do that they need to sell enough of it to keep up the R&D, i.e. they needed to ship desktop chips in similar quantities to Intel instead of only servers.
