> the idea that this could become a weapon against disabled people

Possibly you're taking it a bit far there, but at least in England I could see that being the case. The lengths they go to to stop people getting benefits are ridiculous.

For example, Scotland now has devolved powers for benefits, and are being much more generous: Having a baby? Here's £300. Is it your first? Here's another £300. Twins? Another £300. Then they make sure you can apply for all this online.

In England they tried not to have an online presence because, "we don't want to make it too easy for people to apply."
