Technically people still fly the old Boeing planes that don't crash. The 737MAX is still not in service, and there is a likelihood that it may never go back into service. All future orders are cancelled, and there isn't a clear pathway to the plane re-certified and more importantly for people to trust them again.

High trust systems require just that, high trust. And once broken it's hard to re-establish.

Crypto exchanges certainly have their fair issues of downtime, but don't forget that crypto exchanges for a long time operated purely for early adopters as crypto wasn't something that everyone traded. There was also less availability of competition, because again the industry was newer and there were fewer choices.

And certainly Coinbase helped to popularize crypto trading and they had their fair issues, but I don't believe they had an outage of this exact magnitude, and again they were in an early adopter area where mistakes are seen as part of the process. If not expressly, then at least subconsciously.
