These all have validated what RMS has been saying for years, and you actually have to be quite ignorant at this point to just dismiss his viewpoint.
I am mostly browsing HN during my european daytime. Lots of people seem to comment on stories during my daytime. Do you mean his detractors are predominantly American? Do you think they have a particular political allegiance too?
(Not from the US)
Even if things have changed such that only a third of HN users are in the US, that's still a lot of people sleeping. Though I suppose I am implying that more of RMS's detractors are from the US. On one level, it wouldn't surprise me. Even though RMS's reputation is global, most of his writings are in English, and his homepage is currently focused on North-America-centric topics: https://stallman.org/
But I'm going to make a guess that HN is still busiest when America is busiest, judging by the time frequency of submissions currently in the /new section, as compared to what it will look like at 9am east coast time.
Also, RMS doesn't insist on any freedom of end users to distribute without cost. Only on you not limiting their redistribution.
Now, that makes some licencing models impossible, sure, but those are hardly the only way to sell software.
What he's good at doing is pointing out that certain things are not in our interest.
People care about free software as much as they care about politics : only a few know enough to make a difference...
I think free software as a concept is great, but everything I've ever read from RMS sounds psychotic.
Everything I've ever read or heard from RMS sounded extremely consistent, logical, common sense and down to the earth to me.
I always thought that people don't like him because he's stating some inconvenient truths about proprietary software and because they are pissed that they cannot use GPL'ed software for their closed-source, proprietary products.
To me, RMS is basically a modern reincarnation of Socrates.
