Amazon might not notice that you stopped shopping with them* but if you take that same modest bit of disposable income and spend it on art bought directly from artists, the small electronics projects of your friends, helping people in dire financial situations and the the local theater all of those people WILL notice. It will have a massive impact.
*But, also Amazon does notice. Especially as more and more people do this.
Maybe you think "I can't cut out X just yet" and there are practical reasons that make it hard. That's fine, but keep thinking about it.
You can find a way to wiggle free. It's OK if it takes some time and planning.
The next big one I want gone from my life is YouTube. This one is hard, though. I think the first step would be to at least use the alternatives for those creators I like who bother to offer one.
I don't know how I'll wriggle free from YouTube just yet, but I'm not giving up on it because it's "hard" --
I always try to use Invidious to link videos.
