it's insane Github reports PR stats. I always knew this would happen. But never so publicly. You just assume that your management is looking at it constantly and basing their decisions on it. Because why wouldn't they. Their entire philosophy is "never let a metric go to waste."
All this does is encourage bad behavior. Not squashing commits, throwing up tons of one line changes. Remember that contest Digital Ocean did for Hacktoberfest? Remember what a total shitshow they caused on Github? People were making egregious commits for a fucking t-shirt. Now imagine real money on the line.
Technically you can do and undo the same thing a trillion times and have a trillion commits. In the end your net impact in the code will be zero, yet you will be the PR champ.
You can send PRs updating typos in documentation, or PRs affecting the core aspects of a project.
You can send 100 PRs full of tech debt or 1 that makes the thing run 100x faster.
PR counts suck as a way to measure work.
