The issue is people used to pretend they had disabilities (I know it's wrong but it's not hard to get a doctor to write a letter for depression or anxiety and before anyone jumps on me I have been properly diagnosed with both of those things but I know people who claim to have it so they can park on campus or get extensions) and then they're getting a free laptop out of it.
When I was offered a laptop I didn't mind paying the £200 because you won't find a decent laptop for that anyway.. That said I wanted a mac so I just bought mine myself and claimed back what they would've paid
