That's not how experiences work. If someone says "I saw X" and you say "I didn't see X", that doesn't necessarily mean X doesn't exist, it just means you didn't see it. Sure, the person who saw X might have been hallucinating, but you don't have enough information to know either way.

It's a little weird to so strongly believe that a rare, intermittent bug (no one suggested it's "widespread") couldn't exist with a messaging service that gets a ton of traffic and has to support nearly a billion and a half people across the globe. May want to examine what biases lead you to having such a negative response to something like that.

Also consider that even if you have 1000 friends for whom you are "IT support guy", you've still interacted with fewer than 0.0001% of all iPhone users. You are several orders of magnitude off from a representative sample, especially if we're talking about a rare bug.
