Everyone on this thread (well, 99% anyway) are talking about privacy. If you are using anything more powerful than an Etch-a-Sketch you don't have any despite usage of Little Snitch and VPNs and such, and it will only get worse. Use the old sneaker-net if you want more privacy, although the recipient will probably just enter your information into their computer and so much for that. Time to move on.
But,has anybody noticed that Apple can turn off usage of (apparently) any app on a Mac, including stuff that didn't come from them in the first place? That seems to be scarier than an issue of privacy that you and a hundred lawyers can't effect anyway. I was on Mojave during the Apple hosing of their network, with only a passive connection to the net at the time, and nothing would load with any speed, or at all - Firefox, Gimp, Scrivener, etc. Notice, these are not Apple Store products.
So, lets say that some troll company decides that Firefox has blatantly used a patent for the movement of a mouse sideways to access the scroll bar and convinces some clueless judge of the horrible damage being caused by the theft. So a DMCA is issued to Apple requiring them to kill all usage of a product they have nothing do do with. See the problem here? Can't do that? Baloney. Someone can issue a DMCA takedown because your mailbox is painted in a color that I have patented. Will it succeed? No, but in the next weeks you can't get your snailmail until you have spent many thousand of dollars in the legal sector. Many, many thousands.
Or Tim Cook leaves and some bean counter MBA takes over and the first thing he brings up in a meeting, in the Big Round Circle, is the terrible problem of all of these third party programs being used on Macs all over the world that are not doing anything for the stockholders. "I need you to work on that, immediately." Guess what some of the suggestions will be...
Hmmmm.
