Yes, people do. Thankfully we as a community aren't bound to corporate shareholders, so it doesn't matter how many people choose to use it, we don't have a need to increase users. While we don't have a fiduciary duty to be kind for similar reasons, I think it is generally a good idea to do so. In my experience when I have used words/phrase like "everybody" "nobody" or "people don't" some have told me they found it off-putting or belittling when they are in the minority so I try to avoid it but I still find it hard sometimes as that is not the way I was taught to speak in government indoctrination camp so there is a lot of de-schooling I need to do.
