Definition of Legal Tender "coins or banknotes that must be accepted if offered in payment of a debt."
By this definition Bitcoin is not legal tender anywhere in the world and probably won't be for a long time to come. This is just governments posturing and making themselves seen to be warning their citizens about Bitcoin, while they figure out what the hell it is

They don't give a shit about businesses or debts, they only care to enforce use their own currency which they can print to pay taxes.
