nothing makes me more wary of a company than one that doesn't let me use my 20 year old VoIP number for SMS. Twitter, instagram (probably FB, if they ever do a "SMS 2fa" or whatever for me i imagine i'll lose my account forever), and a few others i can't think of offhand right now.

i've had the same phone numbers via this same VoIP company for ~20 years (2007ish). for these data hoovering companies to not understand that i'm not a scammer presents to me like it's all smoke and mirrors, held together with bailing wire, and i sure do hope they enjoy their yachts.
