It seems like Boeing could easily make everyone feel much more comfortable if they would simply release some info about what they found about the increased amount of lift. If it's really a "slight lightening of the controls" (one quote I remember reading was that you would barely notice if you weren't actually looking for it) then wouldn't it be a no brainer to release some actual test data and allay everyone's fears? That would immediately show that the airframe itself is pretty much as safe as others and that MCAS was really just needed in order to comply with regulations.
The facts that Boeing is telling as little as possible at every step of the way and that the authority of MCAS was increased ~4x it's original implementation makes it seem like what they discovered was much worse than the minor issue they make it out to be.
The counter to "Boeing is saying very little because they have something to hide" is "Boeing is saying very little because for MAX right now less news is better than more news".
I think Boeing has been saying little over the last few weeks because they realize anything they say starts a new news cycle and it's best for them to stay out of the news till they have good news to report.
If they did some elaborate presentation on nacelle lift and stick force not being significant some tech savvy people would feel better about the state of affairs, but some non tech savvy people will start to worry about nacelle lift and stick force and stalling and falling out of the sky pretty much every time they get on a Boeing product.
Given Boeing's reputation is much more damaged than FAA's reputation, Boeing is going to keep mostly quiet till FAA approves return to flight, then start putting out pressers about about how safe flying is versus driving, decades of improvements in safety, etc.
Yes I agree completely
