It’s not Facebook I care about, it’s whoever wrote the post. I’m a photographer. When I find people pirating my work from social media sites I send them takedown notices. If not wanting people distributing my work makes me a corporate stooge, then so be it.

There's a difference between art and a statement of facts. What we're talking about here is mostly a statement of facts, written with the objective of informing the public instead of profit (the fire department doesn't rely on online "exposure" to fund itself).

What does the person who wrote the post lose by having a small subset of people ordinarily unable to view their original public post get to see the contents nonetheless?
