We too use Confluence and it's abundantly unbelievably awful. * Super bloated and laggy * Hard to get your data out/migrate to some rival system. Did your technical writers spend a bunch of time typing strings into a table using the Confluence table building GUI, and now you want that data as a .csv? Too bad, hope you want to spend half an hour in copy-and-paste + reformatting hell. * Impressively broken search (e.g. if you create a page named "foo" and then search for "foo," you'll often get pages of unrelated results that do not include your page called foo) * Can't natively show typeset math. Doing so requires plugins that are somehow both expensive, broken, and only compatible with narrow ranges of Confluence versions. * Gross nonstandard markdown dialect These are just the shortcomings that I can think of right now. However I think even Confluence is probably better than submitting PR's for docs changes as the OP mentions, since at least it's a wiki.
