The thing is the APL has already norticed and ignored the agst, a walkout now only punishes the players/owners who have likely already objected to the decision - not the APL (who I know includes the owners). Given the retraction of the owners names and repost of the decision it seems ill convdeived to walkout on thise who have voiced their discontent at this decision. Not going to the finals will make a massive impact. The NSW Gov has paid money to host the finals, hitting them in the pocket will mean there are some serious questions being asked.
This is the only thing we can actually do to show our displeasure, beyond an easily muted social media feed. Ongoing demonstrations send mesages to the NSW government and the APL that this will not be profitable.
If the players and owners are punished, then they also feel the pressure to reverse this abortion of a decision and will continue to push back against the APL. The pressure mounts internally, and cracks (such as the Victory chair resigning as an APL Director & WU making public statements against the move) start to open. Its kind of a core function of protesting, which you continue to demonstrate a complete lack of understanding of.
