It just didn't fit into a tweet. ?

I just wanted to point out that these legal terms apply to any kind of content you put online. I bet that even in your own webhoster contract there will be a paragraph where you allow them storing/processing the data on their server on your behalf.

Some companies tend to define a broad range of granted rights in their terms of use. They usually do so to avoid updating their terms on every minor change, requiring them to have the whole legal team going over every single word again, informing their users, asking for consent, and so on. So you always have to take these terms with a grain of salt, if it's "we just do the legalese dance to cover our asses" or "muhaha, evil world domination!!!1".
