I would keep a lookout for ISPs doing things like zero rating or other roundabout ways of breaking net neutrality. Arguably, net neutrality is already broken in the US since the current administration isn't going to enforce the current policy. As businesses find ways to make more short term profits here, others will probably follow the same tactics elsewhere.
Although foreign nationals cannot (effectively) write to US politicians, you should feel free to donate to pro-neutrality organizations like the EFF[0].
