It basically says Internet Service Providers are forced to block Cloudflare IP addresses as LaLiga claims it is used to illegally stream the soccer games.
If they are using their ISP’s DNS server they probably don’t even need to use DoH or DoT, just switching to a independent DNS server is often enough. But yeah, otherwise using an encrypted DNS connection should also fix this.
