I do think this is bad UX. The warning message (which basically says "this button doesn't do what it says it does") is commingled with a bunch of other less-important warning messages.

It's also a bit ambiguous-- it seems to be focused on how it will change the settings and last modified date. I could see how one could read that as "this action will create a copy of your files [and then delete the old ones] rather than moving them directly", warning you that your file metadata will be impacted.

There's also the problem that these warnings are everywhere in AWS console so you develop a bit of blindness to them.

So they have a pretty much wrong button name ("Edit Storage Class" --> "Copy to a different storage class") with an ambiguous warning message commingled with a bunch of other warning messages. I'd call that bad UX.

That being said, 8 months is too long for this bill to be considered AWS' fault. and the fact that he's been working really hard on his movie is irrelevant and comes off as whiny
