When Google lastly absolutely deserted its deprecation plans final 12 months, it was solely inevitable that the CMA would start to step again and finally exit stage left.
It’s been a journey, although.

However the CMA determined this isn’t a problem since Google is retiring that API, in addition to so many others within the Privateness Sandbox.
“Having thought of the session course of, the CMA stays of the view that it has affordable grounds for believing that its competitors considerations not come up,” the CMA wrote in its determination.

These developments definitely mark “the top of an period,” mentioned Stephen Dnes, a founding associate at boutique legislation agency Dnes & Felver within the UK.
The query now could be what comes subsequent, he mentioned.

In different phrases, the battles over knowledge entry and honest person selection are removed from settled. And so ongoing vigilance stays important, mentioned James Rosewell, co-founder of Motion for an Open Internet, the advocacy group that filed the preliminary criticism in 2021 that bought the CMA concerned within the Privateness Sandbox within the first place.
“The CMA must control this example as Google is a recognized recidivist,” Rosewell mentioned in a press release. “[It] may simply U-turn once more and threaten the interoperability on which the open internet depends.”
