at least sila may napatunayan na sa industry, not some random person in a forum... well, it's still your choice...i'm choosing the big players...selling or not, they stayed for so long in the industry, di naman sila tatagal ng ganyan if wala silang credibility...how about a random person offering those things in a forum? it's still your choice whom to trust, i'd probably still trust those big players na may napatunayan na sa industry than some random unknown/anonymous person in any forum. i mean, aminin naman natin, would you rather trust your data with some unknown person in a forum or those big players na may naptunayan sa industry (Google, cloudflare, opendns, nextdns, etc.)? i bet you, yourself, will choose the latter, coz really, you still use them as your upstream dns in AGH, right? and even the VPS provider you're using.
