I didn’t say that ISPs are disabling IPv6 because it has any connection to Bittorrent, I said that IPv6, on one hand, and Bittorent-accelerating features, on the other hand, are two things that some ISPs in various countries may want to block. For example, in Poland the router that Orange forced fiber customers to accept for 2019 came with closed-source firmware, and while there was a hack to enable IPv6, the ISP – who alone had superuser privileges on the device – issued a command to the router each night at midnight to disable IPv6, because it considered IPv6 a "beta" feature not meant for wide use (a limbo it has been stuck in for years now). The customer, without access to the router internals, had no way to permanently override it. Fortunately, if I understand correctly, EU legislation is phasing out any obligation to accept only the ISP-provided router.
