"Quarantine soirees" and digital freedom: does any of the live streams described here respect freedom?

The usual forms of digital oppression are

• Requiring nonfree software, often with DRM. Warning: this may be Javascript code; to check for it, use LibreJS.
• Identifying people.
• Imposing an antisocial contract ("terms of service").

Experience suggests that all of those streams are oppressive, but I'd like to know if any of them is not.

If you try one and find it to be oppressive, I hope you will not go ahead with installing that nonfree software, entering your personal data, or agreeing to the terms. Get a copy of some music which does not oppress those who listen to it, and listen to that instead.

It would be useful to inform the organization's personnel of your objections to its computing practices. Keep in mind that they have probably never thought about these issues, never even heard the idea that there might be something wrong with the usual practices that they imitated or were taught by some "expert". So be prepared to explain, and not in an angry tone.

For streaming, the program they should be using is called IceCast.
