one guy deciding to change 90k articles unilateraly is kind of insane indeed.
i find grammar obsession on the internet to be insane overall. you ever use the wrong their/there/theyre and have some guy reply with some unhinged comment. such odd behavior
The other thing is that writing on the open internet means that potentially many people will read the writing. Good grammar is borne out of routine, but this only works if the people practice the right thing - if they practice the wrong thing, then next time they'll potentially do the wrong thing by habit. So really, good grammar depends on reading texts with good grammar. It's also how we pick up vocabulary. Putting these things together, I think people owe it to each other, and the collective humanity, that they produce quality writings on public places.
