While I recognize that, as a business who needs reach, they kind of need to be using these websites where everyone is, I really wonder how difficult it would be to mirror everything they post to some more open and accessible location (a self hosted webpage, anything). I can't blame them for using Instagram/Facebook/whatever, but I can blame them for using nothing but that site. It would almost certainly get very little traffic so it wouldn't need much bandwidth and costs should be low, and it would be a lot more consumer friendly.
