The way you raise a point about missions being the basis to politics and then provide the immediate counterpoint someone would make to show that this mission ("everyone should be able to communicate securely and privately") is caused by a political opinion, is strange.

> But saying that the narrow politics of that mission means the organization should be broadened to take additional political stances that would exclude people who otherwise would participate in advancing the mission?

They're not really excluding anyone. If you read the blogpost, they're not even stopping their technological partnership. They are just stopping co-branding themselves to avoid being seen as directly associated with Mullvad. That doesn't exclude anyone. Co-branding is a position of added trust on top of the baseline of being aligned with anyone who shares your views, isn't it expected that an organization might be pickier if it has to sign under another organization's brand?
