We use it when, for any reason, a person who could easily use something related to their field, doesn’t use it. What it means is that if someone who could be using something because they know how it works, isn’t using it, there must be a reason.
We have a similar saying in Denmark, something like “shoemakers kids always have holes in their shoes” but in this case it’s more about that the people in the profession don’t prioritize their own craft. I’ve seen this with electricians where whole house is done but electrical sockets aren’t installed but for IT I think it’s more about distrust towards developers (takes one to know one)
Ahh, the impression I got is that one makes it sound like they are avoiding it because they can’t be bothered to while the other actively avoids it because its bad.

I think that is the most “correct” interpretation of it. Maybe they’re saying that it’s been bent over time.
