I don't think it's all telemetry. I suppose telemetry could be designed in a way that preserves the users privacy to an extent that is compatible with their native assumption. I suppose that design also depends on what you're building. If you're building a website, I think it's fairly reasonable for you to store my IP. That's inside my expected privacy loss when dealing with a remote party. I have to connect to your computer, much like i have to physically walk into a store. I don't mind you remembering that I was there. Running a compiler on the other hand feels more "private" to me somehow. My expectation when using a compiler is that it won't send anything to anyone, because why would it? In general I think our industry is starved for relevant and foundational ethics research, outside of the FSF at least.
