Switching over to CCS is already happening in Europe because of regulation. The Model 3 is sold with CCS instead of the Telsa connector as part of that: https://www.tesla.com/en_GB/support/supercharging I would not be surprised to see similar legislation here in the US, but we are typically massively behind on things like that. And it would likely be done as it is in the EU, new chargers would be required to have the standard connector. Retrofitting old ones is optional.
Competing on charging networks is tough. The charging cost is determined in large parts by energy cost and rent for the space. Customers have some ease-of-use effect to get a membership at a large network, but brand reliance is low. Thus there is little to gain, but cars from all sorts of vendors blocking Tesla's chargers isn't good for the exclusivity of their brand.
- Tesla obviously wants to have a exclusive network to boost their car sales. Vender lock in greatly helps them.
- The Government / The public want ONE charging network which can be used by anybody regardless of their car brand. In particular you don't want vendor lock in for something basic such as access to individual transportation. (Remember Tesla could easily decide that only "Tesla approved power sources" are allowed to charge your car)
I think it's inevitable that charging becomes a comodity such as fuel. Ad-hoc without registration / app download (or at most one on a national level).
While I agree with your overall point a little nitpicking:
Many certainly don't want ONE network, but compatible competing networks. (Compatible regarding plugs etc. and compatible regarding payment registration)
Basically like gas stations. Different brands but the same products.
Maybe loyalty programs for customers, special conditions for companies etc.
Eventually it makes sense probably but as of now in the US, many people still recommend Tesla if you are doing road-trips. Its still a competitive advantage.
Eventually they will open it up and make money, but reality is that fast charging is a losing business strategy right now. Tons of money in, no money out. Having it as marketing and competitive advantage right now is more valuable by far then the small amount they money they would make by opening it up.
It will be years before they open it up in the US is my guess. Sooner in Europe, but not because of regulation but rather because of the competitive advantage not being as relevant and attempting to get higher utilization.
In e.g. Germany Teslas are <10% of the new EVs sold YTD, I doubt it would make much sense for Tesla trying to maintain a Tesla-only network there, as they have to support the standardized connector and communication protocol anyway. They can only gain by opening up their charging network there.
In the US you have Tesla and CCS. CHAdeMO still exists but it will vanish soon, as almost no new car uses it.
It’s the customers who they should expect money from.
The way Tesla will get "compensated" is that users will pay for the electricity they use. This is straightforward business, not a "free ride".

With every manufacturer accelerating their EV rollouts, there will soon be more CCS EVSEs than superchargers. This move isn't about giving non-Teslas access to superchargers, it's about giving Teslas access to what very soon will be the majority of EVSEs.
It also about tax incentives: the government isn't going to support a proprietary standard.
TLDR Tesla sells an ecosystem. They are the Apple of EVs.

Right down to the atrocious repair policies.
