A little confused about what you're trying to say: Is NordVPN not a trust worthy VPN provider, or is VPN technology itself not trust worthy at all?
Now, if using paid VPN providers is just a useless advice, possibly partially spread by the VPN industry, using NordVPN is very harmful because it seems to be one of the least trustworthy VPN providers because of their close connections with the data mining industry. NordVPN seems to be the №1 because of their immense advertisement spendings that bury the controversy.
