Hi I readded
from the old wiki : https://oldwiki.archive.openwrt.org/about/talks
which I think is a useful overview of OpenWrt and people involved.
Currently it is not linked anywhere from the main page where it was linked in before, because I do not have admin access.
I noticed some issues with older content (prplfoundation site) that was removed and I replaced that with archive.org link.
Having a backup of all or a part of that OpenWrt history archived might also be a good thing to have - it doesnt have to be publicly accessible because of copyright and redistribution issues. (or raw pre-uploaded footage)
I didnt split associated generic links or events like Freifunk or other potential links (feel free to add them/modify) because while they use forks / custom OpenWrt builds they might be just as valid as commercial entities using their own OpenWrt forks and presenting them at embedded conferences or OpenWrt Summit.
