I read plenty on Ars too. Have stayed out of the comments though. I've also
noticed that even on Phoronix, the majority is quite hostile towards
free/libre software and Michael (the author) seems to be wording himself
carefully when writing about GNU and free software; surprisingly neutral and
informed.
Have been tempted to comment on Phoronix, since it's readers are more the
right kind of folks, but it's difficult not to get drawn into a comment war
with trolls. That might just have the opposite effect of what was intended.
Maybe one thing to do would be to subtly inform people that "Linux" is only a
kernel. One of the biggest lies in the "open source" camp is letting people
believe (and claiming) that it is anything beyond that.
