@maija >and an exising account, that makes sense
That doesn't make freedom sense when there are freedom-respecting chat protocols.

There are many fully free chat protocols with free clients and servers - for example IRC and XMPP.

>source code there doesn't matter because its entirely unverifiable anyways
Freedoms 1 & 3 don't matter because the software is unverifiable?
