What happened to the optimistic future than fans wanted so much to be in??
Give up the replicators, free speech, harmonious society, holodecks, better health and pleasure planets? No way!,lol
The only real thing I could find that was wrong was when they (Starfleet) tried to take Data apart for research against his will, or tried to take his "daughter" away from him.
What was weird was that practically everyone else thought there was nothing wrong with it.
Starfleet has been involved in a few scandals or taken it upon themselves to make decisions for the entire Federation.
Maybe Starfleet (at times) may be more of the problem than the Federation itself.
Now, if you start looking at TOS closely, the OP may have some points.
