The problem is that they can't or won't tell the users which data from what parts of the program they sell to whom for what purpose. Instead, they just make you give up all the rights to all your data in a blanket statement. (I think they did adjust the TOS a little bit, but it's still far from good)
Everyone keeps saying this, but no one has an answer for why, if they're definitely going to start selling all our data, they didn't say that in the new terms? I'll get upset when they actually change them to be shitty.
