Free phone numbers to receive sms's are ubiquitous. Its trivial to bypass. Github actions wears the cost as a huge multinational and has anti-abuse mechanisms in place for CI runners but not account signups which again are simple to automate if it means free compute. None of these things are actual solutions, people abuse free tiers to run cryptominers and commit crime, they don't get dissuaded by that. A CC number is a much more serious threshold that solves nearly all of your problems in a day.
