I have a OnePlus phone and I know that to fast charge it I need to use a special USB cable.
But Samsung phones, for example, also have their own fast charging cables.
So why can’t those phones fast charge with the other manufacturer’s cables if the cable is able to transfer enough power anyway?
At the end of the day the cables are simply transferring electricity, and the more watts the faster it should charge, no? At least that’s the way I see it

Nope, that’s not how it works at all. There are tiny processing chips in the cable. These chips negotiate between the power supply and the device to agree on how much current to provide and at what voltage to provide it.
There are standards, and the more companies that use them the fewer cables you will need. I don’t know about OnePlus, but Apple and Samsung both support the same standard, and require eMarker chips in cables befpre they will fast charge with them.
