Well, okay, the drama is probably overstated.
What happened was WotC recently busted a bunch of counterfeiters, so they were releasing an update by way or reminder.
The thing is, the policy is very poorly written and makes it look like they could come down on people running ambiguous stuff like ten-proxy vintage tournaments.
The new rules do two things. They give a very narrow "Official WotC definition" of proxy (May ONLY be created by a Judge, ONLY at a tournament, ONLY for the purposes of replacing a worn or problematic card for the duration of that tournament - hell if you go to the actual page it even says you have to replace the proxy with the real card when it's in play on the table).
Then they follow that up with a definition of counterfeit that could easily be read to mean any other time a substitute for a real Magic card is used ("even when they are marked as non-genuine").
Even if that's not what Wizards INTENDS (in fact it probably isn't), it's still what this rule looks like. At least until they issue a clarification. And until they do, at least some store owners will be rightly worried. Why run a 10-proxy tournament when your store might be denied new product? Granted that's a low risk, but it's still a risk that didn't exist before. And given their normal unwillingness to comment on proxies, there's a good possibility they won't clarify the new policy.
I don't think this was really supposed to be a real change of any kind. The new policy isn't realistically going to stop Johnny Scrubbo from photocopying a proxy for his EDH deck - though it might lead to an increase in GW-style whiners at the casual tables. But there's real potential for serious-but-minor unintended consequences.
