To all . . . good discussion, but please don't violate any laws.
My bigger point to the two rags: Yes, you can charge, its your property, and your right to do so .... but is it a good business decision?
That, I would content, is a "No." The little they make by this paradigm shift will be off-set by the goodwill they lose. The bottom line is, they make their money through selling advertisements, and if people are turned-off by the fees, less will view the ads. they do sell, and then less businesses will buy the ads. Maybe they have calculated that and feel the risk/reward is worth it, but I doubt it.
