A great deal comes to the tight integration of cars and chargers. There are a lot of factors, but the most obvious factor is that cars do not have a standardized charging port location. This means: (a) sometimes stations have multiple cables on different sides, increasing the number of parts and complexity; (b) sometimes when drivers try very hard to plug in amid weirdly shaped parking spaces and non-optimal placement of chargers, they stretch the cables way too much.
Next, electrically different cars also have different battery pack voltages. An Ioniq 5 has a much higher voltage than an ID.4. There's limited room for cars to change DC voltage so non-Tesla chargers tend to need to support a wider range of voltages.
Then there's the fact that the CCS connector is bulkier than the Tesla ones so people use more force, and are more likely to drop them if they have limited dexterity. This also accelerates reliability problems.
