First of all, drivers don't have to run in kernel space. Do you know that? I'm guessing no, based on your comment.
Second, we're not talking about the drivers per se, as those aren't what shows you ads, it's the configuration software and accompanying crapware. Did you get that? I'm guessing no, based on your comment.
Third, there are capability-based kernels, microkernels, drivers that are allowed into as restricted bytecode, IOMMU, and several other layers of security. Do you know that? I'm guessing no, based on your comment.
