I have said that those collected data "will never leave your computer" which means LL proceeds with data gathering but fails in feeding Ledger's server with those data if connectivity is established between LL and Bitcoin Core rather than between LL and company's server.
Or you think they can be exposed to Ledger sever even in this case.
If yes, prove.
A bitcoin node does not have the capability to receive information on what Ledger Live version you are using, which parts of the software you click on, which pages you visit, and so on. This telemetry is sent to Ledger separately to the connection to their node to sync your wallets.
If you look at some of the information posted from the original user who discovered this tracking (such as
here,
here, or
here), you'll see plenty of code phoning home to various web addresses, URLs, API endpoints, etc. Connecting to your own node does nothing to stop any of this from happening.
