There are certainly companies that have experimented with Power, including Google, but I've never heard of any large migrations either.
One other consideration is that Intel chips come with closed source and completely opaque logic embedded in the silicon, such as the Intel Management Engine.
As I understand it Power is now a fully open source architecture and you can get a system with fully transparent firmware (at least if you buy a non-IBM system). Depending on your security needs and threat model that may be an advantage, but I doubt it's a significant enough concern for most companies to justify the lower price performance ratio.
