I just realized that there is so much noise about #Meta and very little about creating template legal policies that instances can adopt that prohibit commercial use of user data.
Whatever you think of defederation there are easy ways to do that. Legal policies on the other hand are complex and require expertise and often money.
Maybe #LawFedi can help crowdsource templates of strict noncommercial legal policies for the #Fediverse so instance admins do not have to figure it out themselves?
