That sucks. This is my main way of video-calling my family overseas. It's also gonna suck for people who use it for 2fa for US accounts (though I think most don't work with Skype and known voip numbers anymore so maybe not a huge deal).
It also sucks for those of us who need to call US numbers from overseas. I need to call a tax prep company and would rather not pay a fortune. Google also cracked down on those proven to be fully overseas with a voice number.
