To clarify, I mean that they aren't as invested in its success as they previously were. Previously, every dollar of investment paid off in terms of hooking people on the Tesla brand. Now that's not the case. The second statement, about bad infrastructure impeding EV sales, is consistent with this. But Tesla doesn't care as much about total EV sales as about Tesla's EV sales. The people who do care about total EV sales (and therefore about cross-platform chargers) are government officials who have set goals for EV adoption. My guess is that these officials will see that they're not going to make those goals with the current infrastructure, and offer additional incentives/subsidies. At that time, Tesla can re-invest in their charger network.
