Here at least, I see it as the complete opposite: extroverts have normal lives, families and lack time that commuting eats up even more, so WFH is a boon to them.

Actual introverts (especially in our computer world) don't have that and often lack a healthy social life, which can be partly fulfilled by the office's interactions. Some of us even are chronically depressed, which means escaping home is important to allow changing our mindset (which becomes attached to a location given enough time).

NB: in Europe and worked mostly for small to very small enterprises.
