To my recollection, in 1985 C wasn't firstly considered an embedded
language; it was considered an applications language (so was assembly,
but we could say that was tapering off).
I believe the explosion in popularity was due to that lesson from Unix,
that you could have a single portable language for both "system" code
and applications code, with a modern looking syntax, that could be self
hosted and compiled to reasonably efficient machine code.
All those tradeoffs and definitions are very different 40 years later,
of course. (And C was far from the first or only language that met those
criteria before 1975. It just happened to take off.)

Having to get a paid consultant doesn't exactly argue for the idea that
C compilers were "easy" - plus it's almost a decade after the period of
high growth. So this doesn't seem strong support for the thesis quoted
by OP.
