It looks to me like the question (as of Revision 2) isn't about computers specifically, so I wouldn't have added that tag.
The [computer] tag, I think, should be used for (English) questions about computers (including smartphones with nearly all the capabilities of a PC), computer accessories (such as charging bricks), computer interface things (such as checkboxes), etc. There's also programming which should be used for (English) questions about programming (and the computer tag is optional I think on these questions).
The tag should not be used for questions where the computer (or programming) aspect of things can be removed, which is what happened in the linked question. Also note that "[n]aming, including naming programming variables/classes" is off topic. (I would not consider the linked question off topic because it has an example sentence.)
