It's common to see this sort of attempt at a post-mortem. Why did X fail? Because they did something that personally affected me in some way. Not because of any of the other million things they might have gotten wrong or missed. I see it often on threads that discuss Firefox's drop in market share - it's not because Google spends far more to market it's browser, or that devs short on time test only on Chrome, or Firefox is behind Chrome on security, or any other reason. No, commenters on HN will tell you that Firefox's share dropped because they deprecated the APIs behind niche extensions that a tiny fraction of their users used.
