You say that in a way that suggests that Google being a market leader is what caused or allowed them to develop a peak user experience. To me - and I suspect others too, given the downvotes - this causality is in the opposite direction to what common sense dictates. And simply pointing at the correlation doesn't help prove your case.

To me, it looks like Google achieved a market dominance because they had a great product, but quite quickly they began practising anti-competitive behaviours and before long the user experience began to degrade.
