Although I guarantee they would run it into the ground without him. I just have a feeling. The people going after Mullenweg are not backseat drivers, they're backseat critics. They have no idea how to drive, they just know when other people are doing it wrong.
If you don't want people like Mullenweg treating your business like a toy, try not having an internet monoculture. There were plenty of competitors to Wordpress that didn't have an insane database schema, but web programmers are herd animals. Somehow they made the only competitor with traction Drupal, which was way worse. You all chose to hitch your wagon to Mullenweg (and DHH for that matter), now it's their wagon.
They both also made it easy to fork at any time, which is evidence that their enemies are parasites imo. Mullenweg is literally fighting private equity that doesn't want to host their own infrastructure because it wouldn't be profitable, but they also don't want to contribute. And the internet cries for them, because the internet was looking for a bargain.
