Not everyone wants the software/OSes we run to automatically send data elsewhere. I bought the damn device, I own it, yet somehow it/the company decides that some things it comes across on it, can be sent to the company?
No thank you, I prefer consensual computing.

No downsides for you, with your requirements/use cases. If the user has a requirement of "Doesn't send anything to anyone without consent", then this is obviously a downside.
