Can you back this up with a list of merchants/exchanges who will not go with Classic? (links plz)
Do you have a list of every merchant (there are thousands) that will update to Classic in a 30 day time frame? You don't. I can't create that list either. Until someone states that they are willing to switch, it is reasonable to assume that they won't (or won't in time).
Adapt or perish. That's the way life works. Ask Charles Darwin.
