Microsoft has won approval from European Union regulators for its $69 billion acquisition of Activision Blizzard.

In its review, the EU, like the UK CMA, focused on cloud gaming, but unlike the CMA,The EU believes the deal can go through because Microsoft has already made commitments on cloud gaming.

But apparently the CMA does not agree with this view and has issued a strongly worded rebuttal.

Sarah Cardell, head of the CMA, insistsThe commission was wrong to approve the deal, saying that "while we recognise and respect the Commission's right to take a different view, the CMA stands by its decision."

The CMA also sharply diverges from the EU in its view of the cloud gaming business.

The EU has given Microsoft 10 years to set the terms and conditions of the cloud gaming market and create a harmonious and diverse market.

But the CMA, for its part, is decidedly more aggressive,That Microsoft would replace today's free, open and competitive market with one that it controlled.

So far, CMA has become the biggest obstacle to Microsoft's acquisition of Activision Blizzard.
