    Jitsi Meet is a good alternative for video calls as an alternative to Zoom. Privacy-conscious people may also consider jami.net (works only 1:1, so there are no group chats), briarproject.org, or getsession.org.

    Yes this list was directed at direct Slack alternatives, so a Zoom alternatives list is a different matter. As mentioned Jitsi is probably the most feature rich open source alternative to Zoom (cloud based and can be self-hosted). There is also video conferencing now available as a plugin with Nextcloud so that is an alternative too if you self-host it, but I don't think it has all the features yet. For video a lot depends on how many people need to participate as there are lots of options for small teams but it gets more scarce for larger numbers of people.

    Would be cool to see something similar about Zoom!
