I think that's a reasonable explanation. I know systems that depend on
vacuum (GC/MS, SEM, FIB) often are kept running or mostly running 24/7
because wasting power is much much cheaper than getting some expensive
part oxidized in the presence or air/moisture, even if the part isn't
expensive (it likely is), the replacement service probably is just as
much if not more expensive.

It probably also depends on the equipment's design... a well made
piece of equipment might handle startup and shutdown more effectively,
more gently, while a cheaper one might just cut/turn-on power which in
some cases could add stress. This is probably more of a concern with
things that use high-voltage... lots of bulbs, detectors, lasers,
anything that says 'ionization' on it, etc.
