Later in the article it says:
> Four airlines in the U.S. fly MAX planes: Alaska, American, United and Southwest.
So: Don't fly those airlines. It is your responsibility to punish them.
(It is also the FAA's responsibility to regulate them, but it's increasingly clear that every regulator is captured. So I'll focus on what I can control.)
And since there was an Ethiopian airlines crash, clearly there are also non-US airlines using the MAX, so let's dig more... This website appears to have done the research:

This should help us boycott the correct airlines.

Unfortunately, the route I use most frequently is serviced almost exclusively by one of these bad airlines. I do have some alternatives if I'm willing to take more time though. I guess, if I want to put my money where my mouth is, I will need to start using those alternatives.
