Quality is a little more difficult than just getting your priorities in order, but I do agree that they aren't focusing on the right things in the right way.

I think people really want to believe in an underdog that can make their lives better and give them a better tool—because we're all product designers trying to do the same exact thing. If Sketch's story goes south, what's to stop us from suffering the same fate? It also comes from a lack of understanding of quality and what creates it: people see criticisms of quality as criticisms of the people who built the product, when in fact, quality comes from systems, psychological effects, market demands, external pressures, and so many more complex factors. The psychological effect of "fundamental attribution error" tells us subconsciously to ignore those systemic factors and boil it down to the individual and their abilities instead. And in a community, to criticize an individual comes across as mean spirited, so people get defensive.

That type of defensiveness is the critical challenge to overcome in order to actually begin to improve with a double-loop learning process.

That, and it's just good enough to cover the pareto, so 80% of people are happy with 80% of what it offers. Real value, however, lies in the 20%.
