Logitech actually did drop the ball.

Already installed software keeps running when the cert expires unless the cert is revoked. Apple didn’t revoke the cert. Logitech did something wonky.

What’s even more insane? Apple has their OWN products that are no longer usable without hackery because their certificates have expired.

Then again, the alternative to all this is the Windows world where old drivers are now the method used to shovel malicious software onto the system, so there’s really no winning proposition.

Actually, your car loses homologation and is not allowed to drive on public roads if your manufacturer decides to update the software without approval from the authorities in some countries (like Germany and other European countries)
