This is a decision that the Microsoft CEO gets briefed on, and can veto, but largely an independent subsidiary doing something like this doesn’t come from the mother ship.
I hope you're that forgiving by default to all leaders who's organizations / countries make controversial decisions, and aren't just being a Microsoft apologist.
LinkedIn largely is independent. Especially on smaller product decisions like this. We already had something like this for years as a limited release product. It was called "ProFinder".
With a lot of large independent subsidiaries, the main company CEO’s decision is firing and hiring the subsidiary CEO and not a whole lot more. The parent company’s management often doesn’t have the bandwidth to get deeply involved so will just veto major decisions.
