Not sure I trust myself to reply to Kzanu and Sordid, but here goes:
Games are very different. Tetris, Counterstrike, Starsector, etc. We all discover games that we like, and where we can see a lot of potential for growth. When those games develop in a direction we disagree with or dislike, we get disappointed. That is natural. Your criticism is welcomed, but please don't compare the game to tumors, that's uncalled for. Call it a mess if you think it is a mess, that's fine.
Personally, I find that the games that I like best have the 3 classical layers: Strategic, tactical and operational. For example: Total War, League of Legends, Starsector. Games that lack layers can be fun, but they are too simple to provide lasting fun. I think you will find this to be true for Starsector if you only play missions, never the campaign.
Right now Starsector is still undergoing heavy development with lots of changes. What we have today is geared towards supporting things that have not even been implemented yet, such as industry, meaningful faction warfare, and other goodies that will continue to have a massive effect on how the game plays.
Your comments makes me think that you loved SPAZ (I think we all did). If you haven't played it yet, go and have some fun with it. Then come back to Starsector when you want a game that is more complex, and you are ready to enjoy and appreciate the interaction between the strategy, tactics and execution.
