I don’t think anyone hates SMS 2FA in general, just that it is susceptible to MITM attacks (snooping/interception) than other solutions (device, key, app) as is made clear in this article.
I note, however, that this attack seems to only be possible on VOIP routable numbers, and it’s my experience that banks, etc, will not allow you to use VOIP routable numbers for 2FA. That’s definitely not the case for a naive implementation of sms 2fa as would be done by likely any dev using Twilio, etc.
