this is an easy error to make even for native speakers.

Really? "See's"?

I'm pretty sure non native speakers wouldn't make this mistake.

It's not a mistake native speakers would make unintentionally but I absolutely understand the ESL problems and, full disclosure, still have to remind myself about the rules for possessives.

It looks wrong and the system is wrong I will not apologize for or be bound by the failures of dead dudes

i've heard native speakers are actually more prone to misusing apostrophes because they learned the sounds before writing, while non natives learn both at the same time
