Google is making the same mistakes Microsoft made. Trying to enter into every industry it can thinking it can use it's monopoly power to take over the world. Reality: Doing 20 things mediocrely is not as profitable of doing 2 things very very well.
Result:
1) Constant experiments and dropped products (just like Microsoft).
2) Consumers no longer trust your services to stick around and no longer even invest in your platforms (*see most of Microsoft's offerings).
3) The services you do have aren't the highest quality and your brand takes a hit as being "giant mediocre corporation" like Microsoft instead of "high quality company" like Apple.
The more things change the more they stay the same.
