In my experience this is a feature of startups. The enterprise I work at doesn’t ship releases with major bugs, period. But in exchange they release only once every 6 months, and releases are very likely to be postponed if any defect is found (even if this occurs in maybe 1/10,000 cases).

Discord gets to move fast at some expense to the users, but mostly those users do not care, as long as messaging/voice chat functionality isn’t impacted.
