I agree that Amazon is getting worse in some ways. I keep using it because of the wide selection and the ease of one-stop shopping. And I have various issues with the way Walmart does business.
But I also mourn the increase in ads and the loss of the also bought slider.
Another thing I notice as a dinosaur who still sometimes buys DVDs and Blu-rays is that it used to be easy to find a list of the new releases in a particular week. Some time ago, that ability disappeared. I asked customer support about it, and the rep said being able to search that way sounded like a great idea. Needless to say, that was the last I heard of that. So I ended up on DeepDiscount.com (even though, despite its name, it's more expensive than Amazon). I can search the way that best serves my buying habits.
I was reading an article just yesterday, though I can't remember where. Anyway, it indicated that Amazon was having to downsize so fast because it bet wrong on how long pandemic patterns would continue. Gee, it turns out that when people feel safe going to the mall again, they actually, well, go to the mall. Even people who had transitioned to online shopping long ago are more attracted to the local mall than they used to be. How long that may go on is anyone's guess, but it was a change Amazon missed completely.
