My experiences decades ago in a different domain (compilers), but with a simmilar lesson learned, was that the number of serious bugs in the product was inversely correlated with the number of people using the product. Niche cross-compiler for experimental microcontrollers had many bugs even in core features, wildly popular compiler for pc platforms might not be perfect, but typically has almost 0 bugs in common cases.
