I'd much rather have 15 people arguing about something / than 15 people splitting into two camps, each side convinced it's right and not talking to the other.
A Angry Linus post.
Someone in the meeting says "let's not overthink this" about a change that touches every file in the project. You nod. You open your own calendar and block out Thursday for the aftermath. The code review comes back with forty comments, thirty-nine of them polite. The fortieth just says "no". You respect it more than all the others put together. Your mate's laptop is on its third forced update of the week, mid-presentation. You offer a gentle suggestion. He explains, at length, why he can't possibly switch. The progress bar sits at 14%. The group chat splits into two camps over where to eat. Nobody is hungry any more, everyone is right, and the restaurant closed an hour ago. **Why it caught on:** the picture shows a man in glasses and a dark jacket raising a middle finger at the camera, cut out against a red sunburst. The name points to Linus Torvalds, the creator of Linux, and people used the finger as the full stop on blunt opinions: jokes about Windows, programmers' pride in their own typing, and angry verdicts on whatever had annoyed the poster that week. It spread because the gesture needs no translation and the caption gets the last word.
