It really sounds like you’ve never worked on a product team that actually used analytics tbh.

This is one of the most obvious things people are looking for in analytics. People will always use your product in unpredictable ways to get the whatever functionality it is that they really wanted. This is one of the things product managers are most interested in knowing about because they either want to properly implement that functionality, or they already have it and they want to know if they’re doing a bad job of getting their customers to adopt it.
It’s incredibly unlikely that you’re such an ultimate power user that what you want out of the product is so unique that you’re inventing your own usage patterns that others aren’t also following.
I completely agree that you should have the right to not share your information with anybody you choose. But if you choose not to share any information about your use case with the company that makes the product, then you don’t have much right to complain about it not doing what you want it to.
