I swear MPB makes up "light moisture on internal optics" to downgrade everything you sell to them

Anyone else experience this? I literally have this comment for 80% of the lenses I send their way. Some of these are lenses I've purchased from reputable websites like usedphotopro that had no mention of this before.

Maybe they just bring all the gear they receive to a really cold room before inspecting. It seems like a cop out to downgrade whatever you sell to them.
