Only UNIX based OSes have a single hierarchical filesystem with mount points.

Windows did not choose that approach only to be diferent, rather that is what everyone else outside Bell Labs was doing.

I'll chalk that up as a win for the New Jersey camp.

Coupled with how to make ideas stick when free beer is available.

No. Thompson and Ritchie borrowed that from Multics, see section 2.2 of https://multicians.org/fjcc4.html

My guess would be Microsoft inherited device rooted filesystems from CP/M.

They could have transitioned to single root filesystems with NT in the early 1990s.

There are plenty of other OSes since the 1950's, even if the idea already existed in Multics, and the large majority of those weren't into single file system camp.

There are even those whose filesystem is based on a database model instead.
