Pretty sure many of the cars sold now have a SIM card or something similar which the manufacturer pays for up front. I don’t think it takes much for them to ping periodically with the information they’d like to track and this ensures they get the data.

Still, don’t connect your car to the Internet, as that could give them way more data but I doubt that that doing that alone will completely stop the tracking.

Edit: typo

The worse results likely refers to results for advertisers but this will impact Meta’s ad revenue in the long run.

The article cited an example with almost zero sales with CPMs of $250, which is crazy high. I’d also bet the biggest chunk of advertisers using these tools don’t have sophisticated advertising strategies or resources. Many of them will probably pause these poor performing campaigns and be very restrictive with future budgets until performance improves.

In short, Meta took a lot of money in a short time but didn’t earn much money back for advertisers, so they will spend less in the future and less money make Meta sad.
