I agree with the general free market ideas behind this argument, but I would go further and question why the 30% is considered price gouging. To compare, Envato (you may know them better as Themeforest), charges 55% as their "Non-Exclusive Author" fee: https://help.author.envato.com/hc/en-us/articles/360000472943-Envato-Author-Fee-Schedule https://help.author.envato.com/hc/en-us/articles/36000047294... It seems to me that if Apple (or Google) had decided to charge 20% initially, the claim might be that 20% is price gouging and maybe 5-10% could be considered fair.
