Initial thought is that it's the dumbest thing I've ever heard. So, I'm going to need to buy extra equipment, keep space free for work, pay higher Internet costs (my area is data capped to a fairly low value by default and lifting it just about doubles the cost), and get charged extra to do it?
Second thought is that wow, do we really want to encourage people to NOT save resources? If it's going to cost me 5% to stay home, I will start driving to the office again (clogging up roads, polluting, etc) as it doesn't cost me 5% to commute.
Third thought is OK, I get what they are trying to do, but this is a really bad idea. It's a poorly thought out attempt to prop up what may be failing industries in the future.
