We are allowing large corporations to dictate and push the web toward a closed system. A future where there has to be an App for that, and if you don't keep your head down you will be censored and cutoff from the rest of the online world.
Hogwash, there is more open source software now then ever before.
Also, your software can be as open source as you like, but if it can't interoperate with the rest of the Internet, it's useless. Personally, I don't watch TV or movies on my computer so I don't particularly care whether my browser lets me do that or not. But I would care very much if, for example, my bank's website started requiring a DRM-capable browser. Open source doesn't address that problem.
