Sorry, where are you getting these views from? Every tech company I've worked at, or have talked to people who work at them, become incredibly risk averse to innovation as they grow.
The only time they makes serious investments in innovation is when they buyout smaller companies that pose a risk to their business, or who have innovated and proven that their innovation might actually be useful. And the reason for those investments is more to protect their business rather than to foster innovation itself.
