>I don't either see what's wrong

What's wrong is that the capability to safely serve and share files over the Internet to people you want to serve, safely and with some modicum of security, is perfectly within the reach of the vendors of Operating Systems.

However, these vendors have fallen asleep at the wheel and are allowing basic system services to be fractured at the base (i.e. in the base OS install), in order that third parties might fill the gap.

This is a heinous state of affairs for anyone thats been paying attention over the years, because there are no good reasons we can't just use our existing computers, and their operating systems, to provide the same kind of user experience as one might obtain with Dropbox, albeit without the creepy commercial-control/exploitation aspect.

I mean, honestly, if folks would just have a way to create their own VPN's out of the box, share the details, and set up a peer network as if it were .. y'know .. a function of the operating system instead of something you learn about from seeing it on a billboard or the back of a bus ..
