Unfortunately, some people just can't handle any kind of inconsistency, no matter how small or inconsequential to the story it is, so I wouldn't bother trying to argue with them. I'm pretty sure Adachi isn't so concerned about such things. Agreed, it's also the reason why people reject the canonicity of Portable Ops and Rising or the twist at the end of MGSV. Still, when looked at as a whole, the series has managed to retain surprisingly good canonicity overall.
