As someone who knows little about Tech Solidarity, other than what's shown on their site, it seems like they're a bit different. Sam's group is a little more pointed in the direction of promoting the broader tech community's values into a company, and Tech Solidarity seems to be more about connecting developers to their community and supporting that interaction. Perhaps you can expound?
I've been talking about organizing labor in tech companies around an ethical agenda since December. For example: https://sfbay.techsolidarity.org/2017/01/05/meeting_notes.ht... That said, I'm happy to hear YC preaching from the same Bible. I would encourage Sam to coordinate with the many groups already working to what is apparently a shared goal.
I am sympathetic to your cause.
