The company appeared to have evaluated this in Germany before rolling it out to a broader audience that includes the UK.
There’s no certainty this will prevent another antitrust case against Google. The contending directory sites are clearly noticeable, however they’re ultimately overshadowed by Google’s own details. These may be a little too familiar. Yelp and others grumbled about Google’s “rival links”proposition back in 2013, and the EU eventually declined the idea. This isn’t awfully far off. However, it’s significant that Google is trying to preempt European legal action rather than waiting for the next antitrust case to implement modifications.
