These iMessage bugs were implemented by properly educated and certified engineers. So what's the take home conclusion now?
Can you please prove that to this audience.
Lets assume that is the case just to make you happy.
Then it is certainly a prof that the learnings weren't taken into consideration when setting up the quality certification chain of the iMesssages development process.
Anyway, we're pretty far off the initial claim you made : "it's those poor saps from coding bootcamps that are the reason this industry is doomed".
