You've always had some proportion of con artists/grifters of course but anecdotally it does seem that there is a higher proportion of people in the US who will, if not flagrantly steal, will do things like this especially against corporations that they mentally categorize as being evil.

Society can handle a small percentage of grifters, they've always been there and always will be. The change is that enshittification is mainstream in the corporate world and feels indistinguishable from being scammed. People begin to feel immersed in it and stop seeing the world as mostly honest and instead as mostly scams. Then good faith policies like these return policies get burned by way more people who lost trust in the system. Then we lose those too.
