When I was a kid, teachers taught us that plural words that end with "s" that are meant to be possessive should end with an apostrophe after the "s" and nothing else. I have been coming across more and more people ending those words with "s's". Did they not get the memo or is that construction changing?

ex: "peoples'" versus "peoples's"
