Do you know what an emergency landing does? It means there are now hundreds of people stuck in an airport they're not supposed to be in, so airline staff then have to try to find spots for them on other flights that are often full, if not overbooked, which causes a domino effect that can last days. It means people miss connections, so they have to figure those out, too. The flight I was on, someone missed their kid's wedding because it took so long to get them to their destination. It made airport staff's next 24 hours hell. Oh, and the woman who caused it lost her job and had to pay tens of thousands in fines because it's taken that seriously. It's not just, "oopsie, well let's get a different plane and reboard all the same people."
It's not dramatic to say that emergency landings suck, and everyone should want to avoid them. And if Boeing planes are having that many issues, that's a problem. Guarantee you that the airline doesn't think it's ok, nor do any of the people on that flight.
