This is terrible. This is where Google is trying to control the web even more than they do already. If this sticks around, if this actually happens, then this will destroy what so many have worked to achieve.
Let's actually sit down and think about this. If this happened, there would be some big changes to the web. (Note- this is a quick response. I should write a real paper about this)
First of all, now that people would be paying for no ads, websites will overload their sites with ads, because Google will have the solution that "everyone is choosing anyway". It would make it "OK" to have tons of ads on your site, because there's a solution.
Then, your web experience becomes terrible. For a "small fee", you can keep a "nice" experience- one that used to, and always should, be free. However, if you don't give Google your money, then your web experience is going to be so filled with ads that content will take forever to load. And even if it does load, it'll take 30 minutes to read an article, because every 30 seconds you'll have your regular add popups. Then, you'll have the sidebar ads that follow you. Or the mobile ones that get in your way as you scroll. You won't be able to view content, because ads will have taken over even more than they already have.
Now, in this terrible future, what about those that can't afford Google's "small fee"? They'll be condemned to the ad version of the entire web- one that doesn't load properly, that people have started to discard. The true "web" will be the one where you pay to view. These people won't have access. And, if they aren't able to pay the small fee, then most likely they're accessing the internet from a slow connection. Maybe it's a library that can't afford the fee either. Or maybe it's in the home, and they can only afford small internet speeds and second hand computers. Not everyone has the money to buy a brand spanking new macbook /pro/air from Apple.
So now, 5 years down the road, there's two versions of the web. The one that Google controls and tracks 100% (oh yeah, we didn't even get to that yet), and the one that is so ruined with ads, that the people make a decision. A big one. Let's just get rid of the ad version of the web. You can't use it anyway, so there's no use. The only way to go- is to give your monthly payment to Google, so that you can access the web. Now, you gotta pay to view the web at all. The free web is gone. Google took it away.
There's also Google, sitting on their even exponential growth pile of money, tracking every web user. Sure, there may be other competing services that let you "into" the web, but they're also gunna track you. No doubt about that.
There's so much more that I haven't even said. How will websites determine how much a "view" is? What about requests that are half loaded? How will you know how much it costs to view a webpage? Not all web content is created equal. Definitely not.
There's so many more things. So many more.
We can't let this happen.
