There is a difference between a bug you laugh at and walk away and a bug a scammer laughs at as he walks away with your money.

When I open something in Notepad, I don't expect it to be a possible attack vector for installing ransomware on my machine. I expect it to be text. It being displayed incorrectly is supposed to be the worst thing that could happen. There should be no reason to make Notepad capable of recognizing links, let alone opening them. Save that crap for VS Code or some other app I already know not to trust.
