They might be 'minimally helpful' and they might want to maximize clicks, but
IMO that doesnt equate to 'idiotic', at all. The slowdown was real and they
have no obligation to figure out what caused it.

Think what an ordinary tester would do: install -rc1, see a slowdown, skip
back to v2.6.34. Reporting the 'macro performance' metrics is useful.

As Linux gets more and more mainstream we should get used to
selfish/hostile/unhelpful journalism, just like we had to get used to
selfish/hostile/unhelpful users, developers, etc. This isnt directed at Linux,
this is simply an unavoidable side effect of becoming more mainstream. And
there will be more of this, hopefully ;-)

Thanks,

Ingo
