RE: Park Güell (Gaudi) in Barcelona had free admission until 2020, now they force you to buy a ticket online. Crappy website. Guess what the tourists are doing now.

You are right, It’s really frustrating how places like Park Güell have gone from being free to charging such a high fee, and now you can only buy tickets online. If the system doesn’t work well, it just ruins the whole experience. This trend of online-only reservations might make sense for management, but for tourists, it often just means more stress and less enjoyment.
