Maybe. I need electricity and the Internet, but I don't need their TV service. I agree with your point that we can't get away from them entirely, but I only need the Internet and electricity. I don't need their TV service or the leftist media that I would be paying for with it, so I cut it out. I don't miss it.
I use Amazon because the items I purchase there are unavailable to me any other way.
I have no idea what you get from them that you can't get from someone else, and I won't ask you to give out any personal information, so I'll take your word for it. Everything I need I get from other sources.
Plenty of items I didn't even know existed until I saw them on YouTube, those items are usually available on Amazon almost never in local stores. I do not live in or even near a major city.
