If it’s not open source then it’s an advertisement not an esport
If someone goes to host a tournament and they can’t choose the patch or modify it then it’s not an even playing field between organizers. Think like 2 people go to host on consecutive weekends and there’s a patch between them now the person who hosted first has an unfair advantage in game quality as the players know how to play it
Also if the studio/publisher is hosting an event it’s just an advertisement
What? So if a sports federation changes the rules all independently organized events are disadvantaged? By that logic the Olympics are just an advertisement for the sports not a competition, as the federation usually don't change rules 6 months prior.
Nope, the leagues are allowed to have different rules
Sports are open source, for instance not every football competition has to use blue cards or a competition made a patch to use blue cards…depending how you want to view it
