As far as the specific "no longer restrict political discussion to the politics of the United States of America" rule goes, I think that's a positive change because in general I think the fewer rules and the more you let organic user behavior dictate the content on the community the better, but I also would not be too upset if this got reversed so long as there's some other well populated community I can find to post politics around the world type articles.
As far as input goes, one idea I had (and by "I had," I mean it was something I remember being a thing on reddit years ago and wish someone would bring back) was that it would be cool to allow text posts one day of the week so users could just submit their own original commentary or try to start discussions about things that aren't getting reported on. That might be way too much work to moderate, but I'd be interested in what people would have to say.
Lastly, I think also having one day a week (or maybe one a month) where meta posts are allowed would be a good thing. The moderation here seems to have improved and be in a good place now, but I think a vital check on bad moderation is individual users having the ability to make their case in front of the whole community about whatever issue, because reports can get buried and a lot of people aren't going to take the time to review the mod log and see what's been happening behind the scenes. I think there is some risk that trolls could try to take advantage of a meta post day and stir up bullshit and misinformation, but I feel like this community has developed enough regulars with enough common sense that those sorts of things could be shut down without the mods having to get involved.
