Two question marks

Hallo,
I found in a reading "competitor' products".

I can't understand if the "s" is missing after the apostrophe because of a misprint or if the "s" can be omitted according to some specific rule.

The other question is as follows:

"Does the term "equipment" have the plural form "equipments" ?"
