If name change was some copyright issue, I'm sure, pretty soon we will know about reason for it, because eventually someone will start digging for information and eventually will know who forced Alex to change the game. It can be weeks, it can be months, it can be entire year, but it will happen.
To continue conspiracy theory and make this thread less depressing. Here is possible list of those, who could act behind the scenes or from the shadows:
1. Electronic Arts - after all they destroy game development studios, maybe they aimed at this studio?
2. Acitvision - well, they destroy game genres, maybe they want to end space top-down 2d once and for all?
3. Square Enix - they ruin every game, they get their hands on. Maybe they wanted to turn Starfarer in to anime?
4. Blizzard - they like making Diablo series. Maybe they wanted to make Diablo in Space and Starfarer is good basis for it?
5. Valve - they like making Half-Life series. And Starfarer is what they need to show how awful war can be between Humans & Combine.
6. FBI - maybe Fox Mulder and Dana Scully found that Alex have something to do with Aliens, that visit our planet quite often?
7. KGB - maybe comrade Putin have some personal grudge against Starfarer?
8. Scotland Yard - maybe they found some impossible and inexistent connections that brought them to Starfarer?
9. The Illuminati - they was bored, so they manipulated copyright and entire countries just for lulz?
P.S. Starsector is quite suitable name for this game, so I actually like it.
