True enough, but too, I think Snowden knows both because the public would be less sympathetic for him but also in that what he stole were extensive documents detailing specific our international surveillance programs (including foreign leaders) and NSA's hacking efforts, his penalties would likely be much harsher. My understanding is Winner stole a single set of documents pertaining to Russian hacking of US election equipment.  In other words he was releasing our (potentially) embarrassing bad behavior, she was releasing information of the Russian's bad behavior, less embarrassing for us (maybe for Trump though).
