Soon after an email client was built into Emacs, a couple of memes were circulated: "Every program attempts to expand until it can read mail. Those programs which cannot so expand are replaced by ones which can." -Jamie Zawinski’s Law of Software Envelopment
"Every program in development at MIT expands until it can read mail." from rec.humor.funny. These witticisms were formulated with Emacs in mind as the foremost example. And there remains quite a bit of truth to them in the Open Source world. I think when many devs hear it, they give a little chuckle, and hesitate for a moment thinking, "hey, that's kind of true..."
I want to say that about my PCs... I do have a couple of old Thinkbooks with Libreboot. Learning the vulnerabilities of UEFI on PC firmware kept me awake that night.
