It's like Livertool said. They were supposed to create a system during this year, how they'd block money transfers for the blacklisted casinos. They even made a law, that banks are obligated to keep track if there's transfers to these sites. "Unfortunately" they didn't manage to get this done, because they had simply no money or smart enough people to pull this through.
And no, they've not cancelled anything yet. But the biggest supporter of the Veikkaus monopoly has already said that they're gonna explore the possibility to move into licensing foreign gambling sites for Finnish players. Less than a year after the previous law, where they did forbid all the marketing of foreign casinos to Finland. If that doesn't implicate for the cancellation, I don't know what does.
