I am concerned as well with some points brought up by the original poster, but I think it's a little early to call the developers out as scam artists. If the upcoming expansion significantly increases the quality of this game than there will be little left to argue about when there is newfound incentive for them to create serious releases of new content.
Then, and only then, will we be able to determine whether this game has what I would call a 'legitimate future'. However this game is certainly not a 'pay to win' situation. Most Cartel and Legacy items hardly put a dent in regards to leveling/grinding efficiency beyond the Boost packs. And even they aren't that significant of a change to progress.
