I think we're at the point where both phone and SMS are such insecure and easily spoofed channels that we should basically not be using them for anything related to business or money. Maybe even for communication, given how easily scammers can fake a loved ones voice and phone number.

The screenshots don't show spoofed SMS. Who is going to spoof a +212 or a +27 phone number when sending to the US. It's not that easy to get spoofed SMS to the US anymore. But it doesn't matter if sending from an international number works just fine. Same thing with email, but often worse ... DMARC makes it hard to spoof email, but most email clients only show sender name and not sender address, so it doesn't matter.

Phone call caller ID is getting harder to spoof, with stir/shaken, but I'm not sure that's fully rolled out either... and calls from a 'random' number still get answered, so spoofing isn't needed for normal scams.
