A great way to convince you you've always been wrong:
Step 1: Gain browser monopoly
Step 2: Generate fake security scare
Step 3: Gaslight everyone that only way to mitigate is to get rid of it completely like Flash.
Step 3a (corollary): There isn't anyone available that can fix the bugs because we spent all resources on UI/UX experimentation
Thank you for reminding me that we don't have Flash anymore. I'm counting blessings I forgot I had.
Flash went away because Steve Jobs made an impassioned plea to find a better way and follow their humble browser which only had single digit percentages of marketshare at the time.
