It generally reaches its zenith when some executives realize they're leaving huge amounts of money on the table by not advertising to all these proven paying consumers. When they realize that, they enshittify the product, make fat stacks and then bounce to the next big thing when there's nothing left to squeeze.
There's literally no context where it makes sense for these sociopaths to not advertise to us. They'd put ads under our eyelids if they could. They'd put ads in our dreams.
