It's guys like you on tech forums posting links like that that helped to quickly discredit BB10. iOS isn't without its reliability/stability/performance flaws either.
iOS has many flaws. No one here has claimed any version was close to being perfect, just good enough that the iOS ecosystem (OS, mobile devices, apps, services) can easily hold its own against competing ecosystems, especially ones that are niche, like the BB10. But statements like BB10 "pretty much nailed it right when it landed" aren't going to go unchallenged.
