They're probably referring to this, from http://en.wikipedia.org/wiki/Ksplice. I've read the creator of Ksplice explaining that the dropping of Red Hat support wasn't as abrupt as it sounds here:

Ksplice is an open source extension of the Linux kernel ... It was developed by Ksplice, Inc. until 21 July 2011, when Oracle acquired Ksplice and started offering support for Oracle Linux. Support for Red Hat Enterprise Linux was dropped and turned into a free 30-day trial for RHEL customers as an incentive to migrate to Oracle Linux Premier Support.

Welcome to HN. A photo uploader for hipsters is worth a billion dollars, but real engineering should be given away for free, 'cos those guys don't need to eat, right?

The "real" engineering was done by MIT students. Before Oracle bought ksplice. You probably didn't notice but the whole thing about linux and this "open source" everyone is talking about, is about contributing back and community. Not about buying and shutting down stuff. Guess what Oracle is known for and what RedHat is known for. Both make money.

Haha yeah, call me when your landlord lets you off the rent, because a website he uses runs Linux on the server. Community, right?

Non sequitur my friend. Just because someone contributes to Linux projects, doesn't mean they are a. Not making money for their services, while contributing back to the community he uses to gain his income, or b. he has a job (related or otherwise) that provides him with an independent income.

You seem to be saying that the Ksplice guys don't deserve to get paid for their hard work, because "community, maaann". Which is an odd sentiment for a site based around startup companies, but ho hum. If they had been acquired by Google would that be any better?
