I wouldn't want to point fingers at people this way even if we were talking about unambiguous and agreed-upon instances of errors, let alone in cases like this, where it would open whole cans of worms. It would look like I'm being confrontational against individuals, rather than pointing out a general problem.

On the other hand, I think it's reasonable to ask my above question in this context. Given the previous history of discussions about this topic, what is the reason to consider the first explanation as more probable than the second? (And what would be the cause of the change assumed by the first one?)
