True but it's a step removed. The MEPs are directly voted in whilst the EC are not, they're "voted in" on account of "voted in" people assigning them to the EC.

I mean nobody argues that the FED governor is voted in, right? In reality a lot of people argue that they're unelected and yet making decisions that affect everyone.

The commissioners are a few but the people who make the actual bills and policies are clerks and bureaucrats who were never elected neither directly nor indirectly. And while the commissioners do change, the EU bureaucrats never change.
