I have developed an instinctual reaction to automatically deny permissions like remotely that for any website, and I think most people have. Websites asking for permission to send notifications provokes the same irritation. I think - "I am in the middle of doing something, I don't want to stop and think carefully about permissions for some vague and abstract future encounters, I want the annoying dialog to go away and the site to get out of my way."

Notably though: If some dialog like this came up even on a specific site like Youtube where I would almost invariably benefit from granting those permissions, I think there is a huge percentage chance I would knee-jerk deny the permission even when if I stopped to think about it, denying that permission would probably make my user experience worse. Lastly, there is an almost infinitesimal chance of me ever seeking out the settings to re-evaluate my choice on this.

In incognito mode every time is the first time. No thank you very much, there are way too many "don't show this again" messages to go through already.
