Facebook immediately comes to mind. Does google even have an ad-free version? Youtube nominally does (though that doesn't stop channels from running their own).

YouTube and Gmail do. I have both ad free. Google search does not. Facebook only did in Europe afaik, but I’d argue it’s not priced fairly. I don’t use most of meta, but would love an ad free instagram. But even if I were in Europe, the price is 20 a month. If I used other meta products that might be fine as a bundle, but is absurdly high for just instagram.

Most newspapers require payment but have no ad free option either.
