If they are selling level 1-49 gear on their cash shop who really cares? If you pvp in the 1-49 bracket, all your gear is normalized to that of a level 49 character.
When you hit level 50 you gear a free set of starter pvp gear, which is good enough to replace all of your leveling gear and start Hard Mode Flashpoints and Story Mode Ops.
Unless they are selling top end game gear in the cash shop no one will care about it. I really don't see a problem.
