Europeans can use ad supported models without resorting to surveillance capitalism. They can even use targeted advertising without it. You don't need to have people's entire internet history, a full list of their past sexual partners, and their GPS coordinates to push ads relevant to a person's interests. The spying is entirely unnecessary, and there's a history going back long before the internet even existed proving that ads without the spying are effective.
Privacy laws don't prevent Europeans from offering ad based services on the net, and being limited to providing more privacy friendly services will make those services more attractive to consumers outside of the EU as well. There's a lot of opportunity created when you can't simply fall back on the most exploitative practices the US allows for.
