Oh, for fuck's sake.
For one thing, I'm talking about the people that are posting things on Github, and Github itself is just an example. You can replace it with "a personal website on a server in your living room" if you prefer, although I suppose that's just an ad for your ISP's services?
Secondly, you are not the product. You are never the product, unless you live in a country where slavery is still legal. "Inclusion of text and image content in HTML sent to you" is the product Facebook et. al. are selling, but that doesn't quite have the same ring, does it?
