Just one data point, but at Spotify we have almost all our stuff deployed in our data centers. ~10K machines, all bare metal, barely any virtualization, in a handful of sites.
It's just cheaper and easier for us to have a lot of hardware racked and stacked and then spin it up as needed without having to worry about virtualization. Experience for our devs is pretty much the same whether they're provisioning a bare metal machine as it would be for a VM.
This is so hilariously wrong I can only assume it's from a marketing brochure.
