uhm actually, yes someone DID force them to release in that fashion... the consoles.
Imagine a world where CDPR said HC would release on all applicable platforms on December 4th but did not give a reason why. Console players don't feel alienated, PC players don't feel like they get to beta a full release before console players get to join them to beta a full release, and HC developers get more time to work out the kinks.
No, the beta comment isn't a slight toward CDPR. It's modern gaming. Every full release is another testing phase. I have no idea if doing it the way I've described above would have been beneficial to CDPR either. In any sense of the term.
