I don't think there's a need to be sardonic; the full paragraph that I believe you're referencing goes on to talk about other common sights and elements of various Seattle districts; the complaint that some Seattlelites are putting forward isn't "we want a decrepit city" it's they want
their decrepit city.
The complaint about the changes Amazon and other companies are making is not about keeping the city in a state of disarray and filthiness, it's about control over the tone and feel of the city, preferring that a single corporate entity not be able to set or dictate the tone/feel to accommodate their interests. Even if there is a net positive as a result, the local residents have no choice in the matter - as was written in the article, those parts of the city are no longer Seattle in some people's minds, it's Amazon's territory.
I'm not condemning or condoning this position - I did live in the Seattle area for about 5 years, and while I loved it, didn't really have the same historical attachment most Seattle folk have, and they love their city, what it was, is, and what it can be.
It's not too difficult to empathize with the position either; suppose, in a rather silly example, that a wealthy business whose owners had a love for early 1900's german expressionism moved to your city (which you feel a connection to); over the course of a few years, a large part of your city begins to take the form of stills from The Cabinet of Dr. Caligari or from Metropolis. The owners clean up the area very well and bring in new trendy restaurants that meet their aesthetic vision. Even if you agree that the area has been changed for the better in terms of infrastructure and economics, are you really satisfied with having expressionism forced on you?
Again, this isn't to say that feelings should override progress with civil infrastructure improvement, but there's a bit more to the gentrification effect, specifically from the tech world, than just a bunch of grumpy people angry about losing their run down and decrepit land. People have seen what happened with San Francisco and they're scared, and rightfully so; while the standard of living in Seattle is decent, the average wages are no match for SV style tech money.
