Google most definitely does many things better than anyone else. GMail is still, to this day, IMO, the easiest and most user-friendly email client. Why? Because it makes use of Googles #1 search algorithm.
But they were late to the party when it comes to smart-phones. And how did they play ball in that arena? They made a product and gave it away, all the while knowing that doing so would be a great way to compete, without actually competing. And why did they give it away? Because it benefits their core business of search.
Why do you think they are giving away Google Play cloud? Because it will benefit their search business.
Wait until Google decides to get into whatever business you yourself are engaged in? And they start giving the same product you sell for money away for free.
I just don't like the drug-dealer business model. Services and Products that have value should command remuneration.
How is Google's search algorithm helping gmail exactly? Better ads?
