It reeks of trashing your benefactor, who gave you well-written free software, which you then made insecure with your own patches.

If you remove the roof of your car with a chainsaw and are inevitably injured later, is it the car manufacturer's fault they didn't offer that model as a convertible from the factory?

The better question is why are people still trying to assign blame all these years later? The IT world dodged a bullet but has moved on (and likely didn't learn from their mistakes as supply chain attacks are steadily increasing).
