We're still buying tons of things from IBM. Storage, Linux, automation, data analytics...
Part of it is the old guard saying "Let's see what IBM has" when we're looking for solutions, but they do provide a pretty large group of established products. They're already in, as well.
They are one of the larger MSPs globally, they own RedHat and Hashicorp, SPSS is the backbone of the global logistics industry, and IBM Cloud does have decent traction in the financial services and logistics space.
Must be hard to generate new sales for their deadass mainframe tech.
