This is probably sound business advice, but it's also a bit sad to shift the goal from trying to create "great software" to "not horrible enough to make all potential users run away".
Well here's the thing - developers have a finite amount of time on which they can work on something. Instead of spending that finite amount of time trying to create great software causing the release to be delayed, you could focus on the core functionality, with a slightly subpar user experience, and start delivering value to your users earlier.
