The player dont need to accept bro, just the org. When u play for a big org, u have a contract and u "belong" to them. They choose ur future later.
If u get to c9 and give them 10million dollars for a player like "JT". They probably will sell it immediately. Cause they wont profit 10m in a single major even if they win it. The sponsors probably dont give all this money to them too...
Anyways, is all about money. And players dont have a lot of choices in this scenarios.
Bunch of orgs dont even worth 10million dollars with all players together lol xD specially the CIS region ones.
