No because in sports you have rules that you must follow or there are consequences. This bug is considered an exploit and therefore it is against the rules to use.
Yes but this is Esports. Bugs are famously used competitively. The entire super smash brothers melee tournament circuit uses bugs to wave run; if you don't use the bug you won't be competitive. People practice using this bug and others like skipping animations. Most competitive FPS games had something similar, like being able to reload cancel or bunny hop. Things that are legitimately bugs, that you won't learn until you hear about them.
Yes, bugs are used competitively but communities will often come to consensus on which bugs are allowed and which aren't.
I think for the most part when you see a bug it's easy to tell if it'll be acceptable for competitive use. Bugs that allow enable more counterplay or raise skill ceilings are usually fine. Bugs that give you an unfair advantage or go against the spirit of the game are usually not.
FWIW I think bugs in the latter bucket should be fixed asap. While you can forbid exploits in a tournament, these kinds of bugs can ruin ladder play.
I wonder who sets these rules? Like when wave dashing came to the competitive super smash bros scene, who decided that this would be allowed or banned? It seems to me it would depend how widespread it is. Maybe the tournament runners already knew how to wave dash so it was in their interest to keep this technique they already mastered legal, versus if they didn't know how to do it yet they might have banned it, like how they've been so careful to empirically place each character into different tiers for the sake of balance.
I can see how leaning into exploits for competitive can ruin the noncompetitive community, and later take out the competitive one that feeds off this community. I used to play chivalry: medieval warefare, which was a lot more fun of a game before the competitive community figured out the frame perfect meta and ruined the game for everyone else who doesn't have hours and hours of free time to throw at practicing the metagame alone, which is most gamers I imagine.
Bunny hopping is an exploit that characterizes counter strike from other FPSs actually. It's a glitch that takes practice to use effectively and was never an intended feature of the game. People use scripts and mods to use this glitch more effectively.
In tournament play you are allowed to bunnyhop without scripts. It's harder and less usefull in csgo but still done. Most servers aren't gonna ban you for bunnyhopping unless you are doing nothing but bunnyhopping around the map the entire game. You won't get a vac ban.
That the mere existence of rules is not enough. They must also be enforced.
Basically, I think you're letting Valve off the hook. Sure, the competitors shouldn't cheat, but Valve should also make sure they create an environment in which cheating isn't incentivised. In the world of software, a few years is a long time. Leaving a known bug that gives a massive competitive advantage unfixed for that long borders on negligence, especially when the fix is relatively trivial.
They are enforced and, again, this exploit was an example of that.
Yes Valve could do a better job at supporting esports. But there will always be in-game exploits as well as out of game methods to cheat so ultimately it is down to the individual participants to cheat or not.
Also these tournaments are run by third parties on third party servers. Valve isn't even involved except for a small role in the once a year majors (that haven't happened for like two years now). So saying this isn't enforced just because Valve didn't fix a bug makes no sense because Valve isn't the company that enforces these things anyways.
