You say no, Apple and Google do it anyway
Hi folks. Below is a download link, and a streaming link if you don't want to download to a BBC world service podcast. You might find the first item of interest if you have a mobile phone; iPhone or Android. If you opt out of sending Apple or Google data, the phones do it anyway whether you like it or not. This podcast discusses this issue. It would appear according to the Podcast that Google is more culpable than Apple, anyhow, you can listen for yourself. Walter.
