Why on Earth do people not run ad-blockers on Facebook and Instagram? I never see ads on either of those sites.

Lots of people don't know how to use browser extensions.

Some people don't like to use many browser extensions, like me. I've never been bothered by the ads; sometimes they are even useful.

Half of the content of both of those sites is ads, even if it poses as part of the regular flow (sponsored feeds etc).
