What is wrong with ads? I personally dislike them and prefer to just pay for services, but it seems that majority of people prefer "free"-ad-supported model.

I’d argue that it’s not specifically that they prefer it, it’s that they don’t understand and appreciate what they’re selling to get whatever service without paying money. Now that we live in a world where everything is collected, aggregated, sold, and weaponized regardless of you paying or not, maybe it doesn’t matter much anyway.
