That's not how it works. The amount of data that would have to be copied and transmitted and stored casually would exceed the capacities of YouTube. Unless you implement a sophisticated filter to let an AI decide what is worth transmitting... while also finding records on personal information (name, location, age). You'd have to employ people who pursue something that is unethical for no direct monetary benefit other than illegally using the information captured. Now this is probably what Google, Amazon, Facebook and Twitter do, but that's more obvious given how people just hand them their information voluntarily.
An anti-virus would have to do something that is entirely not in realm of their purpose - and people could notice and report it.
It's John McAfee my dude. He can probably bring Jack down himself.
John has been collecting data off all our computers since the 80s. He literally scanned every bite of it. He has everything.
