There's no guarantee that posts related to tech that are also related to political stuff will avoid being flagged.
Even when there is a relationship with tech political posts are generally removed if they don't align with a zeitgeist of modern America that seems to chose to fall in line instead of resisting unseemly actions by the new government.
The vast majority of stuff on HN I've seen about Trump and DOGE has been negative.
You seem to be saying HN will promote pro-Trump stuff and delete anti-Trump stuff. That's simply false. I can give a ton of highly upvoted anti-Trump posts.
