Laugh at or complain about Ubuntu all you wish... but this type of effort really puts Linux as a compelling competitor to Windows for enterprise desktop users. Rather than paying for the Windows software license and then Microsoft or 3rd party support for the OS on top, the fees would be for dedicated operating system and package support against criticial vulnerabilities. Wouldn't a business rather have something that "just works as it is" over the long term, rather than something that leaves sysadmins holding their breath every Patch Tuesday with Microsoft randomly shoehorning in "features" here and there that have to be shutoff in GP editor?
More people using Ubuntu means more will be comfortable switching away from mac/Windows. Plus the free software components benefit from having a dedicated team securely supporting the packages over the long term.
The longstanding issue that remains is all the industry-specialized software either crappily-coded or riddled with DRMs and whatnot don't support Linux well yet.
