Politics wasn't "almost forbidden". We did an experiment for a few days just to see what would happen. (One thing that happened, btw, is that many people didn't hear the 'experiment' part and jumped straight to 'politics are banned from HN forever', which was never the case.)
The policy then reverted, as planned, to the way it's always been: most politics are off topic, but not all (https://news.ycombinator.com/newsguidelines.html). If there's an intellectually interesting aspect to the story, it's more likely to be ok, while garden-variety politics definitely aren't.
I love politics but it will be very easy to fill HN front page with a lot of political stories now. Just ask people who "survived" this kind of populists presidents around the world.
For example, last December Argentina would be allowed to export lemons to US [1] Today, this was put on hold [2] which is in line with Trump promises but not with a 10 year long bilateral negotiations between Argentina and US.
