This podcast on Curious Minds about Richard Stallman & The History of Free Software and Open Source is really good, since it really clarifies it's history and what free software is all about. Free software, and open source software, is not just about the technical aspects, but also a movement about protecting user's freedoms from corporate interests.
Users shouldn't need to worry about giving away control of what the things they own, and corporations shouldn't have the ability to take control out of users. Once you pay for something, you should have full control over that item.
Even when you subscribe for the use of something, the ultimate control over your personal information should remain yours. The information you disclose to any company should be limited only for internal use, used only for the purposes intended why you shared that information for.
One should never have to have to choose between having the latest tech, or giving up our freedoms. Our freedoms should be respected, and protected, from the onset. The only choice we should be making as users, is what technologies or products you pick up to use.
At the end, free and open software is the one that benefits the interest of the majority. It lends itself better to competition, innovation and to be used by users as they need it to. Proprietary software protects the interest of a few, who depend on controlling users to benefit themselves. So when the interest of those people and the ones of the majority aren't the same, they are going to choose theirs and there is little the users can do about it.
So, its time to start backing FOSS if we want our freedoms stay firmly in our hands.
