Seems quite a baited title, especially given some comments are jumping on Windows or VBA here - the actual title should be "getting ring0 by installing a terribly designed and dubious kernel driver", but that doesn't sound so impressive.
Given that most drivers are software written by hardware companies and, as soon as the device is sold, are just a liability, is this really going to be a huge barrier? How often do drivers get updated, say 1 or 2 years post release?
Same thing as many non-subscription wireless routers.
Sure, they can unilaterally kill any software on their platform, it's perhaps an important thing to note about it and other platforms where this is true. (Answering questions of ownership and user rights that inherently arise from this and other similar facts are left as an exercise to the reader). However, that also comes at the cost of disabling the hardware that the driver serves, at least until it's fixed.
I've had to use VBA many times to work around abhorrent user controls that prevented work from being done.
VBA seems like it, but there is a HUGE amount of negative externalities that are never accounted for when people talk about how great VBA is for business
In some ways it is like CO2 Emissions on Climate change. You enjoy the benefits today of VBA but the technical debt and other externalities cost the business far more in the future
