Unsure what you mean by polemic in this context. Personally I use Mullvad VPN. Good reputation, fair pricing, you do not need an email (u actually cant provide an email for an account) There was that thing where they were raided by Authorities and nothing was found because they do not keep logs. I also like that they have a "Why Privacy Matters" information on their website. Their blogs are interesting https://mullvad.net/en/blog
