> the privacy fight is just completely unwinnable
I'm afraid it is, in the current state of things.
Another depressing example is how we collectively seem to accepted to keep referring to "unique fingerprinting and observation throughout any activity of the web and apps" as "Cookies! :))", while way too many people even blame EU privacy laws for all the purposefully annoying and misleading dark patterns used by the very entities spying on them.
But you can't blame anyone for choosing convenience and preference over a threat that is utterly overwhelming to mitigate, to the point of feeling impossible to avoid anyway.
Not to mention that a number of people rely on very specific UI features -- OP could well be my colleague, who has a muscular condition and simply cannot press "Ctrl + C" without discomfortable effort, or by constantly moving his other hand between mouse and keyboard. Others in turn may even be completely unable to do either, and fully rely on a pointer device to use GUI applications.
The only chance to win the privacy war is by providing and maintaining free and open alternatives that respect and protect your privacy, and are not only on par with, but better and more user friendly than the existing spyware.
