This is just plain naive. Third-party charging providers (or at least their sponsors) would only love to offer only ICE. When forced, they (Chargepoint excepted) built the networks. The CCS Standard, however, was not developed by charging station providers. The only charging station provider involved initially was Chargepoint although they really didn't understand fast charging until Tesla showed how it was done. High speed CCS was promoted by Porsche, as Tesla began seriously impacting their business, as a way to try to one-up the already wildly successful Tesla.
Still naive.
If there is more infrastructure in Europe (probably depends on what metric is use to determine 'more'), it is because Tesla hit the heart of the European export car market early on by soundly hurting BMW, MBZ, Porsche, and Audi sales in the USA. They then, in typical obstructionist nature (an art form Europe has perfected over the millennia) created yet another non-compatible charging standard and ham-fistedly passed laws mandating its use in the EU.
This after completely shunning EV development for the 20 years that folks in the US struggled through, Europe smugly propped up their ICE industry by greenwashing with their lying claims that they had cheap, clean diesel and that it was good enough.
