I can't speak for who you're asking but personally, there's an important nuance here:

I want (some) infotainment features. I do NOT want them baked into the car. Some of my main reasons:

1. Honestly, the reasons are long (I'm a gearhead, I know cars better than I know code, and I've been coding for 20 years), and largely centers around the idea that in my opinion, EVERY single modern automotive manufacture is terrible at UX in their infotainment. Tesla's UI (not UX) is okay. It doesn't deserve the praise it gets imo but at least it's usable, but that's a pretty low bar imo, but the fact that Tesla wants the touchscreen to be the primary interface ruins anything they have going for it.

2. Additionally, one of the beautiful things about Android Auto/Apply CarPlay is that you bring your accounts and media with you in your pocket. When your car is a separate device as opposed to something you just stream to like with Carplay/Auto, that's another thing to trying to sync accounts/creds and manage data, and I refer you to my above complaint on why I have an issue with that. I mean, it could literally INSTANTLY sync the things that I want flawlessly, and that still doesn't actually add any value to me. It at best reaches parity with the phone that's already in my pocket with android auto, and that's assuming the entire rest of the infotainment functions well.

3. I quite simply don't trust ANY automotive manufacturer to do competent user facing software, and I can't think of a single automotive manufacturer I would trust personal data/credentials to (yes I'm already aware they do that to extent, it's why I'm against it, they already suck at it, last thing I want to do is hand over more data into yet another walled garden).

4. Walled garden's suck, and as this is a value add service with no announcements yet (that I'm aware of) of any other manufacturer working with GM's initiative to establish/adhere to standards/specs or facilitate any sort of portability or openness or flexibility. If it's not a walled garden, great, but I'm assuming it will be, and I don't want it.

It's not something I would ever use, so I don't want to have to pay for it. Its presence also implies that there are other things present that I actively object to, such as a touch screen interface and internet connectivity.

I’m guessing it's the -tainmnet aspect of it. If we're purely weather, traffic, maps it'd be fine but the entire focus is on how they automakers can make more money, now longer about providing objectively valuable services.
