Pick one that has a wireguard config generator, so you don’t need to use any client software besides the normal linux wg client.

I’d also look for one that accepts anonymous payment methods. Even if you don’t intend to go to the trouble to use that yourself, it’s probably a good sign if it’s available. Mullvad is pretty safe and served me well until they stopped doing port forwarding. Proton, windscribe, azire, and airvpn were the ones that seemed most recommended when I went to look for a new one a few months ago.

This isn’t really the right decade for that.

Price discrimination just means charging different prices to different customers based on what you think you know about them. Its benign form would be a market vendor asking higher prices of individual people who look like they can afford it, and then really fleecing the tourists who look like they’ll fall for it. In that form it looks perfectly wholesome compared to what the big corporations get up to today: Supermarkets selling smaller package sizes in poor areas at lower sticker price but higher unit price, airlines asking different ticket prices depending what they know about your web browsing history, et cetera. I do not rate it a good thing overall. Even if we take it for granted that international borders are a thing, and services can’t be intermediated or subjected to arbitrage, the rich man in a luxury condo in Brazil paying less for some thing than the minimum-wage worker in New York does not strike me as reflecting any kind of justice.

But this is the Internet. International borders are not supposed to be a thing here, and still aren’t for the most part despite the best efforts of the most repressive governments to change that. The cost of shipping data from one side of the world to the other is effectively zero. The system where it’s broadly true that different parts of the world have vastly different purchasing power is an injustice, it’s not something we should be attempting to replicate in cyberspace. I can route my network packets so that they appear to be coming from any region I choose, and so can anyone who can afford Netflix in any country. It’s not a freedom I want to give up so that big streaming services can extract maximum revenue from each national market separately.

It’s just another form of price discrimination, a crude attempt to extract maximum value from everyone according to their demographics. If they could charge a different price based on the size of your bank account they’d do that as well and it would be to my advantage. It makes a mockery of the idea that market price reflects the value of anything, and therefore of capitalism itself.

Now that you mention it, my policy from now on is to avoid any Internet service that tries to charge different prices depending on what country it thinks you’re in.
