I think there's a huge argument for a "controlled" Windows-compatible OS.
There are a lot of workflows dependent on software and devices that never had a proper update to support past Windows XP 32-bit.
Even if you use license-downgrade rights, it's going to get harder and harder to find the actual bits you need to keep such systems alive.
ReactOS could potentially provide that steady-state-- a perpetually available Windows XP, which is also recent enough that you could see new drivers added and software ported so you could still boot it on a commodity PC.
