If it's opt-in, I enable it. If it's opt-out, I disable it.

For me it's a matter of principle. That people politely ask is both an indication of trustworthiness and how I prefer things to be, so I try to help by enabling it.

It also depends on the way they ask. Mozilla Firefox for Android tells me that I should choose what I share, enabling crash reports and disabling telemetry by default. Even though the crash report is technically opt-out, they ask me in clear terms. I like that.
