As an Uber employee who has seen the company fight one battle over another for the last 4 years, he absolutely deserves most of the credit (and conversely all the blame from the fallouts). Uber formulated the following approach to get ridesharing in the hands of everyone:
1. Operate in legal grey areas to get a product infront of consumers. Build a large enough network of riders and drivers to prove the product market fit.
2. By the time, politicians and the connected taxi cartels realize the magnitude of the change and seek to outlaw it, rally their own voters to back Uber.
3. Under pressure, have politicians clear the path for legalization. This has played out in more cities than I can remember.
Step #1 before #2 is what made TK and Uber different. The level of ruthlessness it requires, I’d have a hard time substituting others in his position.
