I don't think it's possible to separate tech from politics unless it's an extremely narrow focus on strict scientific & technical discussion. The site would lose most of its value under those conditions, as it's populated by humans that interact or collide with politics on a frequent basis in very important ways.

Commerce, communications, privacy, speech, expression, lifestyle, journalism, entertainment & culture, knowledge, societal debate, government, money, wealth - it all increasingly flows through technology/platforms that techies, nerds, geeks (whatever term you prefer) now heavily influence or directly control.

There's no going back, it's all going to get more political rather than less as governments gets deeper into assigning regulations to the Internet.
