Also, if you follow the discourse on anything published by Mozilla in the past 2-3 years—there's been a shift when it comes to how they speak about Googe. It's a marketing move, of course, but I think it's also a sign of the direction they are following.
I believe something will change here, for better, in the next couple of years. I'd sign for a Mozilla subscription if it included services such as better VPN, supporting those who cannot afford to pay directly, but pay with they data instead.
The move towards paid vs. non-paid services creates a risk that we'd end up with two types of internet users, with privacy being the currency of those who cannot afford an expensive mobile phone or a browser not trying to sell you things whether you want it or not.
The history of Guardian (in the past 5 years or so) shows that people are happy to pay for a valuable service just to allow the others to have access to it. Maybe I'm just being overly optimistic here, but I shudder every time I think about the alternatives.
