Buying something is a not a simple issue, there are multiple factors that go into the decision, and for many, buying something is not really a decision either, because the odds are stacked against them. Also, it might be that JD is not horrible to each buyer equally: some might not perceive these issues at all. And some might just treat it as a business, and write off the grievances as business expenses. They are okay as there are also other things to take care of. Amazon is also a company with many criticisms, and yet, they are very popular. And I'm sure the list goes on.

So from an economic pov: it's a market failure. From an individual's pov: because purchase is complex.

Regarding your last point: "Perhaps RTR just isn't as important to people as the tech crowd thinks."

I agree, and still think RTR is very important. For a comparison, take any public health issue. Are, for example, unhealthy foods popular? Very much so. Is it still worth it for the people to regulate it? Absolutely. Issues such as this are not well served by treating it as a popularity contest, because if it would be up to the children, all of the meals would be candy. Experts, who have much deeper insights into the workings of their area can give much better advice.
