canceling amazon prime is impossible to do

Eh, I've done it 2-3 times, it's really not hard. In fact, I usually just get their free trial 2x/year, once before Christmas, and once at the start of summer.

I get the general point though, and I do try to avoid companies like Amazon that manipulate people (e.g. I refuse to let my kids play Fortnite).

I look at what I can do and what I can't do. I can avoid abusive companies, education others around me, etc. I can't change those companies' practices. I can vote for politicians I believe will hold companies accountable. I can't make those politicians vote the way I want. And so on. Avoiding bad companies is something I can do, whining about it doesn't get anything done.
