I'm not sure what recourse the government has. If they just forbid selling the products that would be terrible for end-users. Would it be fines, perhaps, or...?
The EU fined MS billions of dollars twice for unfair business practices in the EU. I'm pretty sure if the ozzies wanted to they could make life hard for MS, Adobe and Apple.
Even if the government is wrong, pissing them off is pretty much always a bad idea. They always have the last laugh.
