Most of it you don't need. I think Stallman is a loon but he was right about the proprietary code making people slaves to it (but probably not in the way he intended).

There is still lots of stuff I kinda have to use but I've managed to massively reduce my use of most of this stuff.

Obviously if your job/business relies on using this stuff then you gotta use it. I wouldn't advocate that you put yourself out on the street for the source code freedoms.
