I had the same observation. I just chalked it up to more cars having LED headlights and sitting higher on the road, therefore shining their light right into me eyes or my rear view mirror.
Weird that (actually enormous) semi-trucks / lorries seem to have managed not to do this, either now or for the past 20 years. It's only the (fake-enormous) light pickup trucks following this trend.
You can thank government regulation for that. The semi-trucks and other commercial vehicles, because they're so large and tall, have sensible regulation designed to prevent blinding other drivers in smaller vehicles.
Pickups and SUVs don't have this, for reasons... I guess the regulators don't want to piss off the large majority of the voting public, who feel entitled to blind other drivers?
The laws allow pickups and SUVs to have extremely high-mounted lights. There's no law against it, otherwise manufacturers wouldn't build them that way. Selective enforcement has nothing to do with it.
