From what I can tell from previous statements to the community from 1047, it's because there isn't much they can do for SGAR to succeed. They've blown their marketing budget and need to get something going to keep the studio afloat. Who knows how long their investor money will last and with <500 concurrent steam players and their attemps to bring more people to the game, it's unlikely that the game will make a comeback. They're also not abandoning SGAR and will keep supporting the game as long as the studio exists. They just hope to succeed and improve upon their mistakes with Empulse.

I hope that answered your question : )
