As to UPS. It is weird. Now, I mostly don't pay attention to which service I'm getting stuff from. Mostly because I don't have the option most of the time, I'm getting it from the service the seller is using.
A while back, I did notice that USPS was by far the best option in the area I was in. They were often faster and had fewer problems. Now, it's pretty much all the same. I never have any major issues with any of them.
Regarding the Zuckerberg/Musk thing, I think it's just mostly an artifact of it being completely fucking bizarre. Two middle-aged billionaires are about to throw down in a fucking cage match. I believe people are mostly rooting for Zuckerberg because he seems to be able to actually fight whereas Musk has strong "street fight/smarts" vibes. The kind of guy who says he doesn't have "conventional" training, but is secretly really competent because of reasons.
- UPS is now apparently the height of professionalism
- Zuckerberg is the hero fighting off Elon Musk
- Microsoft are the good guys reining in OpenAI
Of course, this doesn't really match the common brand view. Really goes to show how Internet commenters are not representative.
