Unfortunately, if you say something about an ISP with no real evidence - even if it isn’t accurate - you will find others who are willing to agree with you. Others then find that and cite it as evidence, it’s the same way a rumour starts, but once it’s written, it must be true
Your VPN provider has some unusual UK end point providers from what i’ve seen (read 3 out of 4 are not used by other respected providers), but i’d start looking closer to home first.
