Not by themselves as company and manufacturer brands, but as a product/feature/object/... etc `nvidia`. 
I think a better question: How can we improve the resolution times, improve the quality content and decrease duplicates in Askubuntu? 
Proposals

1. Have inclusions in tags etc `asus-pc`, `asus-laptop`, ... Having tag `A-B` is not the same thing as `A` + `B`. For example, compare 
      
    - `asus-laptop` + `power` + `apple-mouse` VS `asus` + `power` + `laptop` + `nvidia` + `apple`, where you cannot even express yourself in the latter. Limiting inclusions makes it difficult to study those inclusions. 
    - Currently, there are much duplicates, low-quality content, unanswered threads and copy-pasted answer (plagiarism) under tags `asus`, `apple`, ... in Askubuntu. To go them through systematically, we need inclusions, which helps to find the duplicates, improve the content and think/work for the answer. 

2. Avoid Manufacturer and Company tags but allow inclusions and allow the former if they are applicable etc `nvidia`, ...
