I'd expect Snapchat users to discuss politics on the platform. I wouldn't necessarily expect Snapchat to expend their own resources to explicitly push an issue-driven political agenda that is unrelated to their own line of business.

Most people can decide whether to "continue doing consumer culture stuff" or to freak out about politics without the help of Snap or any other corporation. There's an odd sort of corporate worship/megalomania that makes people think they're morally obligated to "weigh in" on an issue. They're not, and their constituent individuals are more than capable of pursuing their own political activism and/or creating more appropriate vehicles for voluntary cooperation toward those ends.
