This is just a single engineer from a company that not only makes TVs, console, but tons of other electronic (and possibly non-electronic) equipment. Inside every company, even inside every project, and every team in a any company there might be competing ideas, research and whatnot.

For example we use anywhere from good ole MFC, wxWidgets, WPF, Qt, imgui, Telerik and who knows what else...
