Disagree. Because sometimes "x is unusable" is a statement of literal fact
. In a medium where half the stuff is homemade or produced by companies that make massive mistakes there are may cases where things are literally
unusable: Like the 2 page spread in the 4e PHB is literally unusable as a character generation guide and _literally
(not subjectively) says things like "Character name: write your character's name here" and DIY publishers literally
can accidentally print things with actual mistakes which make them unable to be used
and some automated CG programs literally
do not function as advertised and maps sometimes literally
do not match the territories described.
If you are reporting to people not present about things they haven't seen, you have a responsibility to recognize the difference between things that are so mistaken or misconceived they are literally errors
and things you, given your own parameters
find difficult to use. To do less is to do a disservice to the people who put their hard work into making the thing. And to anyone who is trying to figure out whether to buy a thing or not without spending a lot of their own time doing it.
