Unless they are requiring everyone to use 2FA, isn't that objectively worse than having the option of SMS 2FA? I'm sure there are a significant number of people who would just switch back to using a password instead of SMS 2FA rather than having to get a non-SMS second factor, since it is much less convenient than just putting in a phone number.
Well... I think that if they don't require 2FA, then, well, they don't require 2FA, and not having SMS is neither worse nor better.
If they do require it, then I believe the consensus is that 2FA via SMS is a very bad choice. And since Google Authenticator (and other such apps) are free to download and use, it's not really a burden.
