"Moreover, Wikipedia's coverage of topics that would actually be useful to those lacking access to good education is often inadequate."
Wikipedia is an online open encyclopedia. If something needs expanding, go expand it (bringing up issues in the submission process would have been more valuable...and valid...)
If you want online education there are countless sites actually intended for that purpose.
In my case https://www.khanacademy.org/ does a great job with common school subjects and I've sat down with the kids and used it a number of times when they were digging into subjects i have long since forgotten.
