"It's UNFAIR!" is the anthem of whiny children. If these people would benefit from access to Youtube, and we can provide it to them trivially, then by all means, let them have it. If it upsets you when people are given things for free, that's really a "you problem."
They genuinely benefit from YouTube. I saw one guy watching a video on how to use a debit card since he'd never even held one before. They use them to figure out how to fill out paperwork at the SSA and state agencies etc.
