I met up with Co-op Groups Data data ethics person, yes they have one!
They are rolling out a new approach internally about using data ethically and are trying to promote this and engage the wider movement. Not sure how much interest to Co-tech people this is, but if you are doing your own work on data ethics and want me to put you in touch do.
I mentioned Co-tech exists, and they were interested in presenting it at any upcoming meet-up you organise, if there is interest. Also if your in London they are running an open session.
