I would have thought the vax owed more to the pdp-11 culture than the pdp-10. If you don’t want to move the line add a second one. Berkeley Unix really helped things network and hack and that came from the 11 onto the vax.
That's what I think too. The VAX is a lot more like the PDP-11 than the PDP-10. Hard core 36-bit PDP-10 programmers (like DIGEX, who I quoted in response to Walter's comment) were dismissive of and looked down on the 32 bit VAX.
Doug Humphrey's nickname was DIGEX, and he had a PDP-10 in his living room in Westchester Tower Apartments that he acquired from a loading dock at the University of Maryland. It was challenging to haul up in the elevator! It had two power cords, and two of us had to plug them in at the same time, into outlets on different circuits, so it got both hot legs.
He started one of the first ISPs by that name, which was later acquired by Worldcom:

The article also didn't mention the PDP-15, which was the fifth and last 18 bit DEC machine of the PDP-1 => 4 => 7 => 9 => 15 lineage.
