With all the bad stuff that the internet is in an uproar about, there were some improvements made.
- My battery life is better. With the app open, my phone isn't dying after 30 minutes anymore.
- Logging in is much faster.
- There's more variety of Pokemon "nearby". I can't find any of them, but apparently they're there.
That being said, the good definitely does not outweigh the bad. As a developer, I understand the having to take a step back in order to take two forward, but the lack of transparency seems to be the big problem.
