Lennart earned himself a reputation for thinking his own shit doesn't stink, closing bugs against his software as NOTABUG or WONTFIX even when his software was flagrantly at fault. Here is one particularly egregious and clearcut example: https://github.com/systemd/systemd/issues/6237 https://github.com/systemd/systemd/issues/6237 tl;dr: a systemd service configured to run as a user who's username started with a digit (e.g. the username '0day') would instead run as root. Lennart initially closes the bug report and refuses to fix it because he thought such usernames weren't acceptable, despite the kernel and most linux utilities permitting it and handling it gracefully. A good engineer with a shred of humility would take this report seriously, even if he thought other systems shouldn't be permitting the circumstance. To see the lead engineer of a project so important to linux take such a childish stance on a security-related bug was infuriating and demoralizing. This is just one example, which didn't take anybody by surprise. It's his modus operandi. May the gods have mercy on the Microsoft engineers who now have to call him a coworker.
