I can go with refusing the points you said about the mentioned products. Not because I want to argue, but because it's really not the reason and problems it solved for _me_. I just question myself why I use them and have no answer.
1) Rel. Amazon. I can go to the seller's website directly. I guess I used Amazon because they are so good at marketing, so they are the first to go. But I kind of agree that it solves the problem of simplicity/easier access because a seller's website may have a clumsy website. Some people say that something similar is solved for them by Defi.
2) For AWS, I don't use anything you mentioned. It sounds interesting, like spinning many instances, but I never witnessed it being used like that. Except for instances where someone was playing with the tech (and you can apply it the exact same way to EMV). Also, recently I played with Kubespray, a tool to easily roll out a Kubernetes cluster on a bare metal, and now I don't see a reason to use AWS or another cloud provider. Bare servers + Kubernetes is a way to go imho. Maybe the real reason people use AWS is b/c they simply don't know alternatives?
3) For Zoom, I disagree because I am not even sure we always needed to call, honestly. I mean, we have an email and slack, so what's the point of wasting everyone's time on a call. It's just a routine now.
Again, not arguing. Just trying to say that there could be multiple points of view. And if something works one way for someone, it may be completely useless and even stupid for others.
