Never heard of the greengrocer’s apostrophe so I looked it up. https://www.thoughtco.com/what-is-a-greengrocers-apostrophe-1690826
I absolutely love that there’s a group called the Apostrophe Protection Society. Is there something like that for the Oxford Comma? I’d gladly join them!
I see it as being liberated. Besides, while it’ll suck to be unable to fix their problems, if it gets bad enough that they consider other operating systems, you’ll be right there to help them switch!
