[coreboot] How come the community meeting is hosted by proprietary software?

[Taiidan at gmx.com]

Discord is proprietary software, why don't we use something free and 
open source?

I would be more than pleased to set up a SIP server or something to that 
effect (I have only 10mbps upload but I know folks who will give me a 
VPS if I want one).
There are plenty of FOSS softphones for every OS and you can also use a 
desktop VoIP phone so it would be more convenient.
