There was no reason they couldn’t have sold a slightly less locked-down system to researchers at a higher price point —- Microsoft did exactly that with unsold X360 Kinect units (and bundled in a USB adapter) for medical research.
Sony also demoed rack-mount with Cell (https://en.wikipedia.org/wiki/Zego) but it is not clear that it was available in open market
SONY is infamous for going overboard on DRM.
A lot of things can be done given unlimited time and resources, but unfortunately we don’t have that.
