The whole problem with EV transitioning is that the charging requires you to build out infrastructure. By making their standards open they made the infrastructure investment shared. This was a high confidence basis for build-out. Now third parties like ABB produce chargers and sell them to third parties like gas stations. It's a perfectly rational business decision coming from a strategic position of "large greenfield investment and ongoing maintenance required". Obviously things evolve, but Tesla is certainly not in a worse position for the charging infrastructure (the main enabler of their products) due to the open patents decision at present.
