I don’t think having my real life phone number tied to a website or game account is a trivial ask. I’d like my data to be private, especially something as real-life and tangible as a fucking phone number. Sure, there are ways around these things, you can get a fake phone number for cheap (or possibly even free), but that’s rather more effort than I’m willing to put in for most things. If I need to enter a phone number to sign up for an account for something, chances are very extremely good I’ll just decide I don’t need the account that badly. I don’t think I’m alone in this.
