That's being generous. "Nothing better to do" also translates as "works as sales / business development for the gigantic expensive legacy tool you're trying to work around". End of the day, when one guy is spending all their time on your Support, and you don't know why, and they're persistently nonconstructive or just plain making shit up[1], you have to start asking, "why does this guy care so much?". Shortest answer is often "Cuz he's paid to".

So yeah, moderation is great.
