Dangerous position to take. This is pretty much saying that the ends justify the means, given enough time. That because winners write history, that in the moment, doing whatever it takes to win is more important than operating ethically.
Regardless of whether anyone else did it, do you think these are examples of Uber making the world a better place and breaking rules that shouldn't exist?
You're not really asking a question, you know that anti-competitive behavior is not making the world a better place, it's fighting for market share and dominance.
Anti-competitive behavior is often rewarded in our society with higher profits, valuations, and market dominance. For example, Microsoft forcing PC makers to use Windows 95, or Microsoft using Windows to push IE crush Netscape. Look at Google pushing Chrome via all its products to take 70% market share, much of it from Mozilla, or Google downranking Yelp to push its own products.
