If living the FSF moral means being like RMS, you'll never convince anyone. Here is how he browses 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.

This is the behavior of a lunatic, and not someone who I consider tethered to modern society or the economy that relies on technology. He reminds of the guy in "better call saul" who has removed all forms of electromagnetism in his house. If I met this person IRL, and he tried to convince me of literally any opinion, I would assume outright that these are the ravings of a mentally ill person with paranoid delusions of grandeur
I use noscript and uBlock... my wife thinks about that the same as you think about RMS' 12ft pole browsing. However she is just perfectly fine with Linux as her OS for 20 years now. How Linux came about IS bound up with - is thanks to - RMS and his particular place in the autistic spectrum. If he wants to use email as a frontend to the web instead of wget what's really the problem when his other activities have led to net wins that have affected everyone positively? Can you really sum both things up fairly with one word, "Lunatic", because it's not how you'd browse the web?
That's what the role is, say what nobody else will say, make people uncomfortable when apathy is comfortable, and when nobody else will act, take action and rally others against things that are bad. It's not a role that will inspire universal love whomever takes it.
If instead FSF stops with that and tries not to upset anyone it will be dead, not just in decline.
