The fuselages are shipped to Renton by rail as basically complete structures with the plug (or door) already installed. Assuming that this was an assembly issue (as seems likely based on the lack of associated damage from the departed plug, as well as the AD'ed inspection), the blame should fall squarely on Spriit, not Boeing.
While Spirit was "Boeing Wichita" at one time, that hasn't been the case for nearly 20 years (Boeing sold them in 2005) and it has operated as an independent subcontractor since. Spirit is also a major supplier to Airbus.
While an alert inspector at Boeing might have picked up on missing fasteners, given that fuselage portion arrives as a compete, approved assembly, it is very unlikely that there is any task at Boeing Renton to verify that the appropriate fasteners are installed on that door plug.
Unfortunately, QA at Spirit has been an on-going issue for some time - especially with the 737 fuselages (the often-mentioned issue with the miss-drilled aft bulkhead holes also traces back to Spirit.
Interestingly, there was an article in the Seattle Times recently regarding Boeing and Spirit re-negotiating the contract for the 737 fuselages to include improved quality and QA inspections (presumably with an increase in price to Boeing, although I don't think the article specifically said that).

While I doubt it's feasible at this point for Boeing to bring in a new subcontractor for the 737 fuselage, I think Spirit badly needs to step up their game if they expect to receive any future new business (Boeing, Airbus, or anyone else). No airframer wants to be associated with the sort of liability (not to mention bad press) that the recent Spirit screwups have caused Boeing.
I don’t see any relevance to this argument.

The aircraft has Boeing written on the side of it. Customers pay Boeing. Boeing selects its contractors. If they’re crap it is still Boeing’s problem and reflects badly on Boeing as a company.

That is really all there is to it IMO. They are going the same way as all companies in other safety critical industries that cut costs because quality processes are expensive, then cut too much and it all blows up in their faces and costs way more than doing things properly in the first place would.

The sad thing is the public and the workers (who usually turn up to work to try and do a good job) suffer. The people who set the policies get away with it.

I would like to see large numbers of senior managers fired over this; not the factory fitters. That would send a message.
