Absolutely. To me, it's very similar to programming languages. At the end of the day, it doesn't really matter if people use Google's Go, C++, or some other language. What matters is what's produced by it: the actual research and results.

When you see a useful program that helps you be much more productive, you don't really care if it was coded in c++ or python.

The one part Google does care about is being able to sell Cloud TPU, but I don't think that by using this tool you're instantly in under their control.
