Uber either don't really want Bitcoin (in which case, they're not doing it right) or they are just protecting themselves and preventing further problems (this is what I think they're doing).
Uber is having enough issues with governments forbidding them to operate and taxi men blocking the streets, destroying Uber's cars and being generally aggressive to Uber drivers. What happened in France is just horrific...
Apple will not accept Bitcoin in the near future. Bitcoin would probably have to surpass Visa in volume for Apple to accept Bitcoin
Which is funny, because questioning what is "normal" and accepted is deep within Apple's culture and that's a bit what we're doing with Bitcoin, standing up against governments who think they know better than us what to do with our money.
As for Amazon, not sure what to say. Everyone should accept Bitcoin
