That's overly paranoid, and the defensiveness leads to self-defeat.
There's no incentive for Apple to change the spec confrontationally like that, especially if more people use it. People will stop buying or using their products.
From my perspective, no-one's using this ticketing spec any more because of this fear. You have to download apps for all the services you want and view your tickets/passes/cards in those apps. Very view companies export just the card/ticket without an app (when some of them started out doing this), and increasingly they just keep the ticket in their app. The only thing that seems to consistently work for more than a couple of years are my bank cards - presumably because I can pay with contactless.
Those services which have given up using Wallet are now harder to use and less appealing. They create friction and dissatisfaction with every transaction. And now I don't trust Apple Wallet any more (in terms of being useful). I actually feel freer to leave the Apple ecosystem now than I ever have done because nothing works as well as promised. (The two things keeping me with Apple are not Apple benefits, but Google's failings: surveillance based business model and that their ecosystem looks worse still).
