Users care about quality, even if the people buying the software do not. You can't just say "well the market doesn't care about quality" when the market incentives are broken for a paricular type of software. When the market incentives are aligned between users and purchasers (such as when they are the same person) quality tends to become very important for the market viability of software (see Windows in the consumer OS market, which is perceptibly losing share to MacOS and Linux following a sustained decline in quality over the last several years).

You literally just told me the market doesn't care about quality. I don't get what point you're trying to make?

Right, but this magical market you're talking about doesn't exist. That's my point.
