It drives me bloody barmy when people a chuck an apostrophe when writing out decades. It isn’t 00’s, the 00s don’t own anything. One could write ‘00s or ‘90s; because those are contractions, but an apostrophe before an S isn’t pluralisation, it dictates a noun’s ownership.
I see it all the time in professional writing and official documentation. My grammar isn’t perfect but that is definitely a pet peeve.
