Why Microsoft is a national security threat
(www.theregister.com)
This is a most excellent place for technology news and articles.
An administration that were really looking to liberate itself of proprietary software and develop a sustainable policy would analyze its needs and look for software that matches them, not shape their needs around the proprietary software they're already using.
If you start by thinking "what software does things exactly the same as this one I'm using" of course you'll never move on. Microsoft obfuscates their software on purpose so you can never find 100% compatible stuff.
You're living in a fantasy land. The software you're referencing, largely doesn't exist how a corporate environment utilizes it. Even just excel, the employees need it, you can't teach someone 5 years from retirement a new spreadsheet program. Sure you could buy licenses from MS, but I bet if big organizations started doing it, they would stop. Or only sell the entire MS suite at some insane price. Adobe? Haha
