MakeUseOf.com's service has two things wrong:
(1) It's article about 8 Totally Free VPN Services is INACCURATE, at least as of May 14,2020, since ProtonVPN's service is only free for 7 days. That's misleading to call that "free."
(2) Under MakeUseOf's COMMENT Section, it apparently does not accept comments anymore, e.g., to explain why their article is currently inaccurate.
