Android, just like iOS, was designed with the idea of turning the user into a customer for products and services, therefore many things that we take for granted on desktop PCs, often even free, under those mobile OSes are either non existing or proprietary, filled with adware etc. By becoming mainstream they pretty much destroyed decades of efforts in bringing free and open source and standards to the masses.
