I stream regularly my ATC sessions from VATSIM and IVAO. In light of the EU GDPR, IVAO's policy is that controllers who stream must state so in their controller ATIS and if a pilot requests not to be in the stream, the stream must be terminated. The EU's privacy policy is causing all kinds of changes in how global online networks protect user data. This is just one example of streaming and the EU policy. Adding a checkbox/datafield about streaming seems a good idea is this light.
