> Basically every dev I know has to use either teams/sharepoint/office or google docs
I think there is another sizable set which heavily uses wiki. At my work, most people use it (a very small set of people use SharePoint for mainly PowerPoint or formatting heavy docs).
Are those devs not ever collaborating with non-tech people on documents? Also when you say wiki, do you mean a mediawiki instance or the ones included in things like github?
