Don’t understand why people are surprised that a private company would like to hold on to your data and keep it active no matter what you want or think or do.
Maybe because reddit literally says they will allow you to change this on their privacy policy?

anything you do there is just adding to their monetization of your activity … the best thing to do is to do nothing
Well, saving a copy of your content, overwriting it, and then deleting it - I don't see how this leads to additional monetization. It's actually better than doing nothing because it prevents further monetization.
Ditto with deleting of accounts (as opposed to deletion of content) vs abandoning of accounts. The latter means that reddit can inflate their number of accounts in some ways, etc.
