The OP agrees with you... if you continue reading, they wrote
> These patches never went into Portable OpenSSH, because the Portable OpenSSH folks were ["not interested in taking a dependency on libsystemd"](link). And they never went into upstream OpenSSH, because OpenBSD doesn't have any need to support SystemD.
The language may have been harsher than it needed to and therefore could be more easily misunderstood, but I believe you are actually in agreement with them
It makes it sound even worse, cherry picking language like "not interested" as if the OpenBSD folks should shoulder blame for not being altruistic enough.
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).
