I believe these tags are unnecessary for the most part.
There are very few actual cases where a brand tag is beneficial, such as mac where the hardware and the installation platform actually matters and may need specialized experience. And even so, this should really just be used for installation on Mac computers and problems specific to only Macs.
Otherwise, most questions won't benefit from brand tags, solely because it doesn't honestly matter for the question at hand.
Therefore, I propose that we discontinue the use of brand tags unless the problem at hand is something absolutely specific to that brand of machine.
For example, this question has absolutely no need for asus, as it's a general problem that has absolutely nothing to do with a quirk with Asus machines. Conversely, questions like this deserve the brand tag as it's specific to a quirk with that specific brand of device.
