1) This seems a little bit irrelevant to me. If you don't know that you're losing money, you should be in trouble...
2) Pirates are already very strong, especially in 1v1. Having them be smashed by buildings is a feature, not a bug, which is meant to mitigate their power ever-so-slightly.
3) I'm not sure about this. On one hand, it is strange that nuking medium gives you the most bang for your buck, but on the other hand you could see it as a blessing that your resources are entirely destroyed from medium or low. *Shrugs*.
4) I completely agree with those one.
5) I haven't found this to be the case.
6) Hacker array has some niche uses (as YerAnd would love to tell you). It could maybe be buffed slightly, but I would be worried about disrupting the balance of the game—I think a "slightly" faster hack could easily make it OP.
