Indeed and TBH when the part about Crashlytics made me glad about GDPR (although the rest of the message does indeed sound like an overreaction). I do not like when applications i use try and do things that are irrelevant to what the application is all about, especially when these "things" involve communicating through the internet and even more so when i am not informed about it.
I think it's a weak argument to suggest that crash reports are not "what the application is about" it contributes to the ongoing development and stability of an application which you use.
That said I do think there should be an expectation that your participation in crash reporting would be voluntary and explicit.
