Hearing some noise now that the crew may have been trying to control the pressure manually. Seems like this plane was having issues with its auto controllers. Is it possible that they inadvertently closed the valve completely, overwhelming the two pressure relief valves causing the door to blow out like it did? Seems like these plug doors would be the next weakest thing to give way.

i highly doubt AK MX would be to blame. They would state the case that even if they needed to put the pressurisation Auto system on MEL that the plug could have fallen off even on AUTO mode. Would have taken enough cycles. Not armchair QBing how the crew handled the manual pressurising system but who knows.

A recent rapid depressurization at Delta also blew the cockpit door open. Those little cockpit door vents always seem like there's some slop in the fittings. If the can't let enough air pass, then I can see the door glowing open.

If the airplane was over pressurizing, people would have noticed. There were no blown ear drums. The PSI delta was probably around 2-4.
Journalism paranoia.

The cockpit voice recorder data on the Alaska Airlines Boeing 737 MAX 9 jet which lost a panel mid-flight on Friday was overwritten, U.S. authorities said, renewing attention on an industry call for longer in-flight recordings.
National Transportation Safety Board (NTSB) chair Jennifer Homendy said on Sunday no data was available on the cockpit voice recorder because it was not retrieved within two hours - when recording restarts, erasing previous data.
Did someone forget that part of the NTSB checklist or was the flight from and back to PDX so long that the CVR ended up hitting the 2 hour mark and overwriting itself?

It's a 73, were the blow out vents even invented yet when they designed the door? I kid. Sorta. Not really. 🤣🤣
