It's just more communication about the same thing. Started out with just a mention in the release notes and a checkbox in the settings, which clearly wasn't enough (hence your calling it "silently"), then a more elaborate response on Reddit, and now this more detailed blog post outside of Reddit's walled garden. And I'm sure it's not the last we'll hear of it. (I'd be curious about the experiment's results too, for example.)

Advertisement is not free. It's a trick that looks free if you ignore the entire way it functions.

It doesn't take an expert understanding of economics to see that any belief that advertisement allows for a free Internet is smoke and mirrors. The money comes from somewhere, notably from you.

I think thats kind of obvious that the money has to be coming from somewhere. The ads are what funds large parts of the internet. Someone is paying for it, either the people buying stuff because of the ads or the businesses buying the ads.

Whichever way it is, maybe both, it has the side effect of distributing the cost of the Internet. The alternative without ads would be everyone paying for every little thing on the internet, does anyone think, that that scenario is realistic? That would also mean the cost is solely on the people and nothing coming from corporations.
