This is absolutely still a free market. You want the content, you're going to make a choice in what you're willing to do for that content. If it requires you to pay for it or it requires you to install a plugin or it requires you to use a browser that supports the streaming of it, those are all choices you can make. That's the idea behind a free market.
Maybe you should look up the definition of "free market economy". If DRM is part of the price of viewing the content, that's part of the economy. Non-DRM protected content is still available, in the same market, but is generally less sought after in the same way that people are usually much less interested (if at all) in content that does not have a price or is completely free. If something has value, the creator usually wants to receive that value for their work.
TL;DR: This is exactly a free market economy. Anybody can provide content. There is no price fixing. Access to the content is not government controlled. Etc. Etc. The only thing standing between you and the content you want is what the creator/owner of that content wishes to receive from you in exchange for the content, be it money, DRM embedded in the delivery tools, etc.
