Tell your friends that you are not willing to accept their terms of friendship. On multiple occasions I've asked my friends/acquaintances to not post a specific photo that I'm in, and they've stuck to it. They might still keep it, as a keepsake, but it's not publicly available. If I wanted to go any further than that, I'd have to ask myself the extreme question of... "Why go out in public at all" due to all the times I'd have my face or actions tracked.
Unfortunately, it's not as simple as not uploading a single photograph. If Facebook has scraped your friend's (or grandma's) contact lists, the shadow profile has been created, and the friend tracking has begun.
When someone does something that prevents you from going outside, society generally makes that illegal. You might find that some of us are not all-powerful enough to make people do things simply by threatening to no longer be their friend.
Well, you need to look at it a little more objectively:
It "prevents" the individual from going outside because that individual has precluded the idea of going outside due to the possibility of being tracked/photographed.
I.e. Nothing about being tracked/photographed "prevents" an individual from going outside. But that, combined with an individual that fears/hates/morally_objects_to such a thing, makes it so that that individual is compelled to not go outside, lest they be forced to subject themselves to the thing they object to.
Additionally, it's not about "making people do things", and being not powerful enough to do so. That's quite an imposing/forceful line of thinking. It's about "thing X bothers me, what peaceful non-violent actions can I do to avoid X affecting me (negatively?)." And yes, making a regulation against X and forcing people to submit to it through the threat of imprisonment is quite violent.
