This is the main reason; and it applies to developers (they need cloud buzzwords on their resume), it applies to managers (who in turn hire only those with said buzzwords) and it applies to company execs/CTOs who can brag about the complex (self-inflicted) problems their company is solving at the next cloud provider conference, so they can justify yet another VC round.

Run this for over a decade, and you'll end up in a situation where an entire generation of "engineers" is no longer capable of configuring a Linux box to serve some basic webapp and will make up whatever reasons to avoid even attempting to do so.
