I wonder if there's any evidence of how many customers are lost because of dark patterns or general scumminess. I suspect it's not many. I generally try to avoid giving money to any company that actively hates it's customers. For example Amazon, which is the like going to the shadiest third world bazaar and having every scam in the book thrown at you each time you try to buy something.

Same for any company that uses chatbots or otherwise prevents customer support.

But my guess is that people only care about price, and we'll just see an even faster race to the bottom as people get more conditioned to using disrespectful interfaces.

Back to tipping, it's ironically the impersonalness of shitty automated service that enables this. Few self respecting people would ask for 20% tips when they did literally nothing and you served yourself. But a computer interface can shamelessly nag you for whatever.
