I'd also love to hear the B engineers side of how MCAS was specced and built and whether they were put under pressure to "just do it". As somebody earlier said, where's the integrity gone?

Thank you Groundbum - exactly my view too. As to why it was done the roundabout route via Stab tinkering - this seems long to have been a "fix-all" at Boeing and it was probably the obvious adjustment to them.
And while on the subject - refering to AoA input -
what could possible go wrong? a few posts back - well a lot more can go wrong with a rogue input to the stab - as documented over many pages here... than to a feel spring.
If false AoA info were to trigger a false spring resistance, the only result would be a one time hardening of pull input - one time - which could be trimmed out.
