Nah; it's a peculiar form of self-justification by attack. The template goes something like this:
Person A is prominently trying to do something about major problem B.
Person C knows they are contributing significantly to problem B, but is unwilling to do anything about it.
Person A contributes to problem B in a minor, often unavoidable, way.
Person C siezes on this as a reason why problem B and person A are invalid and can be ignored.
Problem B continues on getting worse.
There's probably a good latin term for it.
