More probably, it's just that there is a lot of money to make in taking total control of the user experience. Up till now, we had to deal with this pesky OS, those package dependencies, long cycles, and complicated installation process. But with the Web, you can inject your code almost in real time on the user machine, they don't have to understand anything, they don't have to wait, and you don't have to care about what's under the hood. In fact, the user doesn't even know or accept it's running a software. Now the browser is pretty limited, sandbox and all that, so companies making bank with it want to widen what they can do with it, again, and again, until the browser becomes an OS under their control, and the user machine just a terminal to access it.
