It seems to me that what would make a huge difference would be if someone like @PINE64
would sell a reasonably priced router with enough power and storage to be a basic family server with @yunohost
pre-installed. Just plug it in, set your ISP modem to pass through and you have a working server. It could automatically open the right ports, use the new auto dns setup. Referral fees from in device domain purchases through a privacy friendly registrar could help fund.
Easy is a must here.
