Ironic that this is one case when you don't use an apostrophe to indicate the possessing entity. I suppose the rule is possessive nouns only, not pronouns.
If enough of us make this mistake then maybe the prescriptive half can drop the whole "possessive pronouns don't get an apostrophe" rule altogether :D.
The same goes for "alot", avoiding the use of "whom", and so on - I ain't gonna give up on them!
I think they've given up on this, it's ubiquitous. I've recently noticed that a CLIP model (a neural network for image understanding) gave me image descriptions using "it's" where "its" would have been correct. Hundreds of thousands of dollars to train the thing; no one noticed, no one cared ¯\_(ツ)_/¯
Honestly I don't love HN's title edits. Why can't we have nice blog titles that start with why?
