To translate what happened into HN terms and analogy: the Open Source Initiative is an umbrella organization which advocates for Mozilla, Linux, Debian, Python, Apache and other open source projects.

Riseup.net is similar. It is not a group with a very specific ideology, it is an umbrella organization which many organizations are associated with, inside and outside of Germany. In the case of Riseup.net they are an umbrella for left-leaning groups. As their web site says, they provide tech services like email, web etc.

The raids on five locations were on Riseup.net, this umbrella tech organization which provides tech resources for much of the left.

Look at Riseup.net's mailing lists. Thousands of left-leaning groups have mailing lists there. Riseup is not an organization with a narrow focus. It is like a GitHub or Gmail of the left.

What probably happened is the German police were focusing on one person or group using the service, and raided not the members of that one mailing list, but the overarching umbrella organization that has 999 mailing lists on feminism and such.
