My current pet example for the trend of hiding more and more details from users is an issue I recently had with Doordash.

I was trying to place an order, and it kept failing with a red banner stating "something went wrong" (I'm paraphrasing as I don't recall the exact verbage, but it was one of those completely worthless error messages)

Pop open dev tools ... the server is returning something about a graphql error.

Support had no idea what was wrong.

The problem ended up being that my saved credit card had expired. For fuck's sake, that is a user-actionable error; tell me what the problem is. At least tell me it was a payment problem, since that's probably all the payment processor told you.
