I worked for a certain media company that sold hardware / software in cars with memberships (typically through a deal with the OEMs). For those customers that have the hardware-only experience, a set of testing IDs can be applied that effectively give free membership and can't really be revoked because of their wide-use in initial manufacturing provisioning. There have been multiple independent security reviews pointing this out, but not much can be done about it because of how the trial memberships are applied after manufacturing.
I use it consistently. I, however, do not like the shorts panel taking up a ton of space in the feed now. My subs feed shouldn't have shorts from people I am not subscribed to, but it does.
