probably. Also - lazy ad buys.

There's human effort involved in planning a micro targeting campaign. Way easier (and short-term cheaper) to do some broad strokes ads with a couple ok-ish proxies for your target market than pay people that know what they're doing. So your conversion rates are garbage and CAC higher than it could be, but your spending is on the action instead of front-loaded on salaries/agency fees.
