There's some article that said 90% of computer users are below proficient, they have their routines but get totally lost if something doesn't work...
OTOH, having no support isn't the answer either, especially if the issue is actually on their side, and the user is genuinely inconvenienced.
It would also probably generate more support scams.
This would solve the issue of monkeys wasting support's time while offering a way to get support for those who know what they're doing and are happy to put their dollars on the line.
Does this model actually work? I'm sure there are some reputable companies that could make it work, but I'm not sure I know anyone who would trust Facebook to get this right.
One could crowd-source it, but there's probably a high chance of brigading...
Just offer support to the proficient ones.
