I don't think we've had any Bitcoin bros talking at previous events. We have had sessions on forcing government to open data. Similarly, several session about OSS in the global south, discrimination in data sets, community groups, radical action people can take.
You're very welcome to pitch a talk about whatever you like. We also have an unconference space if you'd like to do something more spur of the moment.
(I'm not on the submissions panel, so I have no say in what gets picked.)
You might like these talks from previous years.
