Whats really interesting to me is that this seems to be more of a huge marketing issue. Pocket IS Mozilla* and it seems like people would be more ok with the integration if they knew this. Now, obviously, Mozilla does need to improve the sponsored stories and not track the user without input, but at the same time, its not a 3rd party in the general stance.
