You're missing the point: if you're going to respond to a matter like this publicly, you had better respond substantively. Anything less can have the effect of making the claims against you seem more credible.
Note that this wasn't a debate about languages, frameworks or methodologies. The OP flat out referred to the company's code as "tangled mess of mindless duplication, half-implemented features and misleading comments" and claimed that only one employee "knew anything about the system." The response here mentions surfing on Wednesday but doesn't dispute any of the OP's claims about the state of the company's technology and technology organization. That looks horrible.
