I haven't seen any web apps that seem to be intentionally unusable, or any belonging to banks, personally at least. I don't think anybody is doing this as a publicly announced policy. But I have seen several websites for major institutions with major features totally unusable on their website, that should be found in a matter of minutes if they had even one QA person actually trying to use the website after updates. It's not announced, but it's hard to imagine it's not intentional.

For my most recent personal example, go onto State Farm's website and try to create an account. Goes to a blank page. It only seems to work right on their mobile app.
