Stallman would probably use GNU wget which is licensed under the terms of the GPL, while curl is licensed under a license derived from MIT/X consortium.

He would probably have someone print it for him, similar to his email queue. I email him from time to time and his disclaimer says this.

I've never heard him say anything bad about running MIT licensed software.

On the other hand, I think I've read a FAQ where he says he views web pages by having a script fetch the pages with wget and them emailing them to him, but I'm pretty sure that's simply because wget is free and does the job (being able to recursively download the necessary resources), not because it's GPL licensed.

Obviously Stallman is modifying his wget user agent to show curl just to prevent fingerprinting him accurately... ;)

I love the idea of someone individually targeting Stallman with ads.

"I am careful in how I use the Internet.

I generally do not connect to web sites from my own machine, aside from a few sites I have some special relationship with. I usually fetch web pages from other sites by sending mail to a program (see https://git.savannah.gnu.org/git/womb/hacks.git) that fetches them, much like wget, and then mails them back to me. Then I look at them using a web browser, unless it is easy to see the text in the HTML page directly. I usually try lynx first, then a graphical browser if the page needs it (using konqueror, which won't fetch from other sites in such a situation).

I occasionally also browse unrelated sites using IceCat via Tor. Except for rare cases, I do not identify myself to them. I think that is enough to prevent my browsing from being connected with me. IceCat blocks tracking tags and most fingerprinting methods."

For the record, Stallman uses GNU IceCat these days.

I don't believe it's RMS because this user appears to "browse" the web interactively. A lot of the sites he hits are on HN so I think he's a user here.
