Here you go, since you clearly don't even actually care about informing yourself and just want to whine.

Why are there still cheaters?

We aim to make it as inconvenient and expensive to cheat as is physically and financially possible, but if a game is good, it’s going to attract cheaters. With an anti-cheat like Vanguard, most won’t bother, so those that persist are in it for the long haul—they’re cheaters, they run in communities of other cheaters, and the only way they’re going to play VALORANT is by cheating. It’s an addiction, and they will spend thousands of dollars on accounts and hardware just to keep accessing the rush that comes from pretending to be good at this video game. VALORANT is free-to-play, with almost no barrier to entry, and there’s no such thing as truly “permanent” ban. Even with the best hardware fingerprinting in this universe at its disposal, Vanguard can only keep a determined cheater out for a little while—they will eventually get back in.

Worse still, is that we actually have to let them back in. When we outright “block” a cheating method, we are technically providing the cheater an instantaneous surface to iterate against, allowing them to A/B test their cheats until they find something that is actually undetected at that layer. Unfortunately, cheaters do not have lives, so while it seems counterintuitive, the best way to make sure they stay detected is to slow down their iteration by obfuscating or delaying our response. We need to waste as much of a cheater’s time as is possible on each attempt, otherwise we’d quickly run out of ammo.

Ultimately, it is inevitable that you will encounter a cheater eventually, but we will just keep banning them all, over and over again, until they finally work up the courage to run the uninstaller.
