It's also just pushing the work of testing onto the users, at which point the effort and cost of testing is much higher, and the brand damage of the bugs is also higher.
Theoretically, there's a big userbase to spread that cost out. In reality, most users just immediately stop using stuff that doesn't work as expected and there are 3 hardy bug reporters left after the exodus, that eventually burn out and then leave in a fit.
The fact that chronically buggy software is a huge turnoff for potential Nostriches is the pink elephant in the room.
