The more I work, the more I'm convinced that product management is not truly a profession but rather a way for non-technical people to insert themselves into a profitable industry.
Realistically you do need someone (vendor or not) to translate 1000's of pages of legal jargon into actual product decisions. There's a tipping point where paying an engineer $x or $y to do that themselves (if they even have the skill to interpret it) is waste of talent.
Why the accusatory and negative tone? How does this contribute to the discussion in a meaningful way at all?
This is fuzzy, but that's because it's not a technical question! It's isomorphic to "what three blog posts on web frameworks did I last read?" (-:
In any case, even if my example were a bad example for some reason, there are definitely lots of technical decisions that are fuzzy. How could there not be?
