I agree, equipping your fleet with the Max is a high risk strategy, another incident anywhere in the world, even if unrelated could be troublesome for peoples willingness to get on the thing.
From what I understand there has already been 22 incidents regarding flight controls on the Max since it started ops again and a number involving MCAS. If its the same issue again I cant see it being long before another accident occurs.
There's also talk of the Max 10 being cancelled if it isn't 'fast tracked' to avoid new rules regarding crew alerting, which the Max series does not comply with, and US congress wanting to probe Boeing again regarding the Max recertification.
