I'd make some snarky comment about the quality of one small but important part of Linux noted for ongoing consternation - sound - but seems that'd be poking a hornet's nest again. https://news.ycombinator.com/item?id=5664202
Intended relevance was raising the issue of what constitutes defects, the range of effects, and longevity thereof. As others noted, some of what were counted as "defects" were little more than semantic inconsistencies or obscure flaws rarely seen (if ever); counting each of those as "1 defect" on the same scale as something that pesters the heck out of a large percentage of users (or drives away many prospective users) isn't quite right.
My poor wording was an attempt to raise the point without eliciting a similar hundred+ responses as the last time it came up.
