I guess that would make sense in a country with incredibly restrictive internet laws or one that requires to report known crimes to the police/government.
The reason why I asked is because I’m skeptic of this, HTTPS (which is also what your Lemmy instance uses, as well as just about every website and application) uses that same encryption. If your VPN provider requires you to give your name, address, phone number and pay by credit card, they likely know more about you and you’re likely less anonymous than with your ISP. So in most countries, using a VPN moves the trust from your ISP to your VPN company arbitrarily.
That said, there are definitely very anonymous VPN providers, and countries where using a VPN from another country makes sense.
