I'm sorry if it came off like that. The mistake in this case was completely mine (bad code and bad testing). The detour on the other two companies was mostly because this way of deleting/recovering stuff should've probably been avoided in the first place, other than that I'm absolutely not blaming anyone else!
Don't worry about all that - there isn't a developer worth their salt that hasn't made a mistake.
But I'd consider having this blog post and HN post retracted purely for future internet checks. It isn't a reflection on you, and your honesty is fantastic. But there is a lot to be said about using a pseudonym when it comes this close to your employers
