I was just explaning the concept of a "broke window falacy" (funilly enough without using the actual example that gave the name to it) and how work merelly being done is not a gain and can actually be a loss because of the opportunity cost (i.e. the people and the resources could otherwise have been used elsewhere and actually produce something of worth).

Also I was just thinking about the Musk-era Twitter rather than the entire Twitter timeline.

As you correctly point out, Bootstrap is something of worth (I would be more hesitant on the "interface" side, as I worked in web interfaces back when they started and that stuff is just derivative and not especially great).
