The provider blocks the IP, not the URL/domain - how to deal with it?

Question

Computer networks

Given:
I live in a wonderful city with two providers. One of them is Rostelecom, the second is Reutov-telecom.
If any URL or domain enters the registry, Reutov-telecom blocks the IP of this site. No stubs, just a connection timeout.
Many CloudFlare IPs have been successfully blocked, respectively, the list of innocently blocked sites has greatly expanded. Wherever I poke, connection timeout is everywhere. Is it internet access?
In technical support, they say that the resource is included in the register of prohibited sites:

The required ip address is entered in the register on the grounds provided for in Article 15.1 of the Federal Law of July 27, 2006 No. 149-FZ.

It is clear that for some reason the provider did not have the opportunity to inspect packets and block at least by domain, but why should users suffer?
Question:
So I'm thinking of going the other way. There are large sites, individual pages of which appear in the registry (YouTube, Wikipedia), but which our provider magically does not notice. For example, the wikipedia article on ways to commit suicide through my ISP opens up nicely. To block such a page, the ISP, with its current approach to blocking, would have to block Wikipedia for the entire city. Or change your approach.
Is non-blocking of prohibited pages a violation of the Federal Law on the part of the provider? How to press from this side? Is it worth doing this (escape plan only towards Rostelecom)?

Answer 1

Unfortunately, I saw only one answer and how you can punish for NOT blocking ...
But the reverse situation - the provider does not want to set DPI apparently ... And stupidly blocks by IP. The law is fulfilled - but what if a bunch of sites hang on ip and I need some? I am writing to the provider - he waves it off, like everything is legal, I have the right. And as a result, every 10 clicks in the search engine - "the page is not responding." Here's how to deal with these?
