Our stance here is that:
1) We are very explicit about what gets sent (only telemetry and crash reporting) and you can see the full list of telemetry events here (https://docs.warp.dev/getting-started/privacy#exhaustive-tel...)
2) For collaborative features like block-sharing (e.g. https://app.warp.dev/block/tbxmeAKsj657aHkPdHpmoY) it's completely opt-in
However, I do believe pretty deeply that every app has the potential to be much more powerful if it leverages the internet and I think the terminal is not an exception. I stand by that but get that it's a paradigm shift.
Please keep the feedback coming though - it's helpful to understand how you think about it.
