The Max line is clearly cursed, and I think it's reasonable to be suspicious of all of the variants in it. That they've taken the newly discovered problematic ones out of service doesn't imply that the ones left in service are good -- particularly since it seems that the problems stem from systemic quality control issues rather than something special about those particular variants.

Have they though? Boeing is the least trustworthy company on planet earth these days. The airlines aren't far behind. The regulators don't seem competent.

I say this as a capitalist - Boeing should be torn apart and sold for scrap metal.I'm sure there are some decent folks there, but that place has turned into a mess.

The ones that are known to be questionable so far, you mean?

They never seem to identify the questionable ones until after something goes to shit.
