●● Linux Foundation Apparently Celebrates Sysadmin Day With a Microsoft Windows Site!


Posted in GNU/Linux, Kernel, Microsoft, Servers, Windows at 1:34 am by Dr. Roy Schestowitz


“Greed is not a financial issue. It’s a heart issue.”


–Andy Stanley


Summary: The Linux Foundation shows ‘love’ to actual GNU/Linux (the real thing) by apparently rejecting it and badmouthing it


WHEN selling the soul of Linux is more profitable than actually promoting this GPL-licensed kernel it’s not hard to understand how the Linux Foundation turned from a supposed ‘charity’ to a massive enterprise and near-monopoly in that space (e.g. events/conferences).


↺ Linux Foundation


They ‘own’ Linux.com. They control or manage the Linux trademark. So why would they link to anti-Linux stories (authored by “swapnilbhartiya” yesterday)? Because they just do and most of them don’t even use Linux! As someone put it yesterday:


↺ link

You go to Google, you look for “Linux” news, a site called Linux.com then shows up with anti-Linux material (this isn’t about Linux but bad devices/users). Well done, Swapnil and Jim. The articles posted nowadays in Linux.com give room for concern. Misleadingly-titled FUD.


“You go to Google, you look for “Linux” news, a site called Linux.com then shows up with anti-Linux material (this isn’t about Linux but bad devices/users).”We’ve meanwhile noticed lots of spammy blog posts (yesterday, Sysadmin Day) from the Linux Foundation in various “Linux” blogs. “Linux Security Blog” participated and “It’s FOSS” did so too. Linux Journal said (in the headline) that “the Linux Foundation Is Having a Sysadmin Day Sale,” adding a promotional link with what seems like tracking/referral code. But that in itself isn’t the issue. It seems like the site in question uses Windows for the server, but we’re not entirely sure. It’s very well disguised (see IRC discussion at the bottom).


↺ participated

↺ said (in the headline) that “the Linux Foundation Is Having a Sysadmin Day Sale,”


It would not be unprecedented for the Linux Foundation to use Windows; applicants apply for a job there using LinkedIn (Microsoft), as we’ve noted before and there’s a lot of Microsoft stuff used by the Foundation’s staff (see discussion below; I know this from my old interactions with Foundation staff). Over the past months I’ve had to resort to humour just to get the point across without offending the offenders, for example:

Yesterday I also noticed this text: “Have directly led revenue growth from $20MM to $50MM, from $80MM to $100MM…”


No, that’s not the Foundation’s chief Jim Zemlin (who sold out Linux… for his 'nonprofit' to make about $100,000,000 per year). That’s what his wife’s LinkedIn profile says. It’s all about money and both strive to grow in just one respect: money! From 20 million to 100 million. What is being achieved? Nothing. A Windows-powered and Mac-powered ‘Linux’ Foundation (Linux only in name). █


for his 'nonprofit' to make about $100,000,000 per year


“Large corporations, of course, are blinded by greed. The laws under which they operate require it – their shareholders would revolt at anything less.”


–Aaron Swartz
