People puzzle me indeed. They guys is not an idiot; he is ignorant just like the rest of the masses. Platform-independent Skype with multi-user video conferencing has been around forever but FaceTime locked to a single OS is much more popular. Go figure. And for a modest fee you can used Skype for POTS communications with reasonable great international rates.
And for that matter VoIP (Viber, Burner, etc) has existed for a long time, the main issue/hassle has been integrating it with a direct dial number (POTS). At one point I used SipGate.de with a Sip application on iOS successfully having a local area code and it had free incoming and modest cost for outgoing. SipGate is no longer available to US subscibers.
I guess blame European companies for poor marketing.
