It helps if the product is so revolutionary that people are willing to overlook bugs. Could you imagine a more mundane product with a TUI that flickered all the time where this wouldn't be a showstopper? I believe the bug is fixed now, but it seems crazy that it persisted so long given how obvious the cause was (clear before update). How many more bugs are in CC? As of a few weeks ago there were 5000 or so open issues against it on github.

The success is undeniable, but whether this vibe-coded level of quality is acceptable for more general use cases isn't something you can infer from that.
