They are standardized, as far as the high power electronics go.
But imagine having to install the "Chevron" app to pay to fuel up at Chevron, no big billboards with the price visible from the street (and prices wildly varying from free to $6/gal), some gas stations billing by minute instead of by gallons, half of the stations hidden in a dense parking lot/structure or "for retail customers only" and 1/10 pumps in the US being out of order.
So the only thing that makes a Tesla charging station different from the rest is that they appear in the map of the Tesla app? That sounds reasonable, but I don't understand how it can be a "killer feature or Tesla" when Ford could just show them in their electric cars.
Tesla have their own custom plug. They appear on the map in the car and the car tells you if the station is full (or partially broken) of people and potentially re-routes you. Tesla charge location also usually have multiple very high performance chargers. Tesla chargers are usually higher at charging that the waste majority of other chargers. Payment is fully integrated with your Tesla account.
So its drive in, plug in, wait, plug out and drive away.
Pretty much non of that works consistently for other networks and the are usually slower and you have to spend there longer as well.
There are standards for the plug, standards, Europe is well standardized, US a bit less, China is a bigger mess. Important to note however, the plug is standard, the payment system on the other hand is not. Or rather it is partially standardized but the software compatibility might not actually work very well or is simply not implemented at all.
