Ya, the vendors of alternating current are the electrical utilities. And the issues your talking about happened in the 1880s, between Edison's DC vs Teslas's AC. Obviously 110V AC won (not 220V) and market forces and regulation have kept that standard and the price stable. The point is that if we feel okay paying for electricity as a service, why not computing? Data ownership and security is one reasonable concern but they're not show stoppers.
