From my experience actually yes many are if you are a paid subscriber. Free services certainly have slow or non-existent support models. But IMO a service owned by a multi-billion dollar company should at least be responding to their support tickets from paid users within 5 business days.

At smaller companies, definitely! It's the bigger FAANG-like companies (and these days Microsoft and Nvidia) that don't care about customer service.

Jetbrains has good support.
