ISP's give us access to the Internet. And we pay them for it. Google makes money via ad aggregation. We already know they were able to do this without siphoning up all your data because they literally made money doing it before 2004 when they launched Gmail. What you're talking about already exists though. User subscriptions for Email, VPN's, Search Engines etc already exist and people are using them. People are paying for them.

People also generally understand that if they aren't paying for a service then they are the product. The thing is though, lots of those people are fine with ads so long as the ads don't get in the way of them enjoying the product. If I open a website they don't need to have a full page ad open up when the site page loads. But they do that anyway and that's what people are largely pushing back against.

Additionally, if these companies want our data? They should do a much better job of safeguarding it, or be held responsible in a meaningful way.
