Depends on country I suppose. The main complaint from me is the difference in price and subscription requirement to even be able to use some of them though.

Subscriptions from major charging providers can easily run 15 Euros a month and for that you get electricity for up to 50% cheaper per kWh. There are also a lot of providers that you simply cannot charge with unless you are subscribed. Payment is only possible through their app or they send you a physical rfid token that's linked to your account.

In my town (200k inhabitants) roughly 40% of stations require you to sign up with the provider first before being able to use it.
