Everyone saying "Yes" might as well, hand over their wallet/purse and keys to their house/car and newborn child. Seriously though if these flawed ideas get passed, you have yourselves to blame when all things fail.
ISP: How can we help you?
Customer: I can't access my internet!
ISP: Well we've been told, you have an infected PC, so you're cut off until otherwise known.
Customer: *insert what you want here*
I was leaning towards yes and then thought about it, read the whole article and firmly said no! This is the worst logical idea, as people have pointed out before. Who's to stop a false attack, against say.. an ISP that won't cooperate? Then suddenly that service is cut off, the smaller services will be disappearing under all these problems. Soon we'll have a global ISP, where it's pretty much a dictatorship. They want full control of our lives, people are too blind to know who "they" really are.
There's nothing here worthwhile, what if you were using an older OS? Not all schools upgrade to the best, would that mean they'd be given free PC's or something? Nope, nothing at all. Just means the whole school as a whole, could be shut down if things are not up to requirements. I've been in public and high schools, who ran from 95 and 98 OS's. Does that mean will Microsoft, somehow extend support for em now? Hardly!
Enforce the rule of upgrading OS to something more secure, and also by the way.. use an AV only they approve of. None of those "perfect" AV services, that don't have major impacts. It's better to take the giant bloatware AV packs, that will cripple your PC and make it it's slave. Then you can use the internet, unless of course that service fails in protecting you. Have fun fixing that one, being all those giant companies don't always work. It's been proven before, it takes multiple ones usually to protect better. No one program is perfect.
