And CS1.6 doesn't have any DRM protection. So anyone can hop into the community servers with cracked VAC. That's the naked truth behind the sudden and huge uproar of cs1.6.

And that is where you are wrong.

What we know as Counter-Strike 1.6 or Counter-Strike nowadays has DRM and the DRM used is Steam. It is not effective though and has been bypassed for any game that ever used Steam as one of their DRMs (yes games have multiple DRMs these days). Prior to Valve buying CS the game was indeed DRM less because it was a mod for Half-Life by Sierra. I believe the last version before Valve bought CS was 1.5, or maybe 1.5 Beta or even 1.4.

VAC is just Valve's anti-cheat system for their games. So bypassed Steam games cannot join normal servers. And you don't even crack VAC when you allow non Steam games to join VAC servers. What you do is tell the server to let everyone in and report as a fake player with a fake SteamID to VAC. You don't get VACed because there is no account behind the fake SteamID and so VAC cannot ban anything. So instead there is always a different anti-cheat on servers that monitors non Steam players. VAC is absolutely untouched otherwise and simply has no effect on non Steam players/games.

CSS has been Steam bypassed, too. Also allows non Steam players to join servers with the same fake player and fake SteamID trick. And guess what... CSGO is exactly the same. I hosted servers for CS, CSS and CSGO and always allowed all players to join (Steam and non Steam, VACed excluded of course).
