The article misses that Sony is Minolta, something I, too, didn't appreciate for years, as I took a photography hiatus in the 2000s.
Almost all digital cameras, mirrorless cameras, phone cameras, iPhones, etc - regardless of maker / manufacturer, uses Sony sensors.
The purchase of Minolta unified sensor tech + software development + lens development and formulation + body ergonomics in one house - something no other maker is able to do, probably aside from Canon (who also uses Sony sensors depending on model) and Leica, which borrows sensors from other makers but has their own imaging tech that they add.
No matter how much money any Nikon, Canon, Pentax, OM system makes, Sony will always be part of the supply chain of those cameras.
Sony and Samsung are both producing a lot of sensors for mobile devices though. For example Apple has used a lot of Sony sensors over time. And likewise most camera manufacturers do not design their own sensors at this point.
(and once Sony makes the money, it uses the same profits from Fuji to compete against Fuji.)
It's a sort of reverse competition, where by Sony is guaranteed victory simply because they participate in their competitor's victories.
