“Now”?

This is nothing new. For about 30 years now Microsoft has been constantly repeating various flavors of this “make it so a thing can automatically and silently run programs as soon as it touches your computer” thing. It’s always done in the name of user convenience. It always ends up being a fiasco. I don’t know why they keep doing it, it’s not like the exact same PHB keeps making the same decision over and over for 30 years. It’s probably one or a combination of the many well documented flavors of stupid that are deeply baked into the company’s organizational culture.

(And before the inevitable response, no this is not defending Microsoft. Pointing out that an organization’s culture is too deeply, chronically stupid to avoid opening the exact same obvious and gaping security hole over and over and over and over again is not the same as saying, “it’s fine, actually.”)
