None of the examples you gave (toasters, windows, paint, and shower-heads) are services. I used YouTube (a service) as an example, because we're not in a world where products are overrun with ads the way services are, but my point was that even the service market has started to offer alternatives to ads.
The idea that the market will bear every product getting service-ized but somehow not offer any ad-free versions is nonsensical, at least in the steady state.
Tangential, but you reminded me of it: it's truly fascinating how incredibly brain-damaging discussion of ads seem to be. Every single thread I've ever read on the topic is full of non sequiturs, nonsensical analogues, glaring logical inconsistencies, etc. The only other topic I can think of that makes people similarly insane is airlines (cf my "why should I pay taxes" uncle complaining about airlines no longer requiring other passengers to pay for transporting his suitcases).
(a) introduce new products that require additional subscriptions (but eventually the company runs out of new products to introduce),
(b) raise subscription fees a tiny little bit every year (but there's a limit to how much any company can do that without angering customers too much), and
(c) break existing ad-free plans into new tiers of service, some or all of which have... ads.
