Taking away freedom
When common people are introduced to free software, the first application which entails their freedom is a multimedia player for the web browser, namely Adobe's Flash Player. Creating a replacement for it is a High Priority Free Software Projects. Let's look deeper into the issue!
Adobe's Flash Player is the de facto standard for interactive multimedia on the web. It is rare to find a website that does not contain embedded Flash files, so the browsing experience of the users of Adobe Flash Player becomes largely biased by one single company. On the other hand, we don't have information about the internals of the proprietary application, so it is theoretically possible that the invoked Flash Player Plugin reports usage patterns to the mother company, which would mean that almost the whole browsing experience of a particular user is tracked.
The pattern behind
Due to the public's demand for an animated web, Adobe conquered a position where every part of a platform: the file format, the content creation and the content player are in the company's hand. This is a monopoly.
Reaction of the free world
Among these circumstances the creation of GNASH, a free replacement Flash player is by far not enough. The real missed thing is an open standard for interactive animated content, which can introduce competition among content creation tools. Without that the whole multimedia web market stays dictated by Adobe releasing newer and newer versions of their proprietary platform, and forcing newer and newer free software users to install non-free software. In my opinion freedom should not follow: freedom should create.
