So, this is the one SV disruptor that is actually changing the world? I hope you didn't break your arm reaching around to pat yourself on the back with that one.
>Outside this little bubble, no one is blinking twice at this,
Might I suggest stepping out of your bubble to realize that the world is not going to end because of the lack of a video conference. People are sheep. Fire is hot and water is wet. "People are not blinking twice" is not the hill you want to die on. You might as well say "people are stupid, and we can take advantage of them". At least that would be honest.
Build an app. If it is good and people want it, they will pay for it. If you want to make it free by selling the data you harvest from the users, then be up front about it and let the users decide. As you stated, people are not "blinking twice". Since you are not up front about it, then any good will you might have earned is out the window.
