And hell, this is commented as somehow "wrong". How wrong is it compared to Google buying out one of the largest Android manufacturer Motorola Mobility? It's even more bullshit from Google's front.

That is incorrect. Software will always have bugs. The best way is make clean, proper tested code and then introduce sandboxing. MS already does this with IE9 sandboxing and JIT hardening. Catches 99.9% of bugs.
