Speak for yourself.
My dashcams upload everything recorded to youtube when they connect to a known Wifi Network.
As with encryption, there are 2 approaches to data slurpers:
1: Limit what they get (but that means they only get the important stuff)
2: DROWN THEM.
(The rule of encryption is that once you start encrypting your messages or data, ENCRYPT EVERYTHING, including your laundry lists. That way an attacker may spend most of his time decrypting your stuff to find you needed to wash 4 pairs of socks. For more fun, make the laundry list a stronger cypher than the others so they think it's more valuable)
