Nitrokey would probably be my choice as both the hardware and software are open source( in fact you could probably build your own if you wanted to). I don’t trust yubikey as the firmware that runs on them is closed source so you just don’t know of it’s actually secure.
People have already proven they will put up with about anything Microsoft throws at them, so they were never going to switch anyway.
Also you still can’t uninstall the bootloader under windows.😆
What makes it even more crazy is 90% of projects are using github/gitlab/gitea or some other modern git platform that literally has a wiki feature built in. And everyone and their dog either knows or could very quickly learn how to use markdown to write the wiki.
If you want a chatroom at least use matrix as it’s open source and privacy respecting. Though IRC is better for a community. And good old forums are best.
