That said, I would argue that there is no Ethereum "account" - it's just a crypto key. In that sense, use on Ethereum is similar to someone using an email address to sign up for mailing lists and to post on forums.
The counter-argument is that your wallet app likely provides the interfaces to do that functionality, which makes the Ethereum blockchains a proper system under consideration.
The post you're replying to says Apple believe it should. Unless you can persuade Apple to change their policy, it won't matter if you disagree.
(I’ll give you that Safari isn’t in the App Store but many other browsers are. It would viewed as anti-competitive for Apple to remove all competing browsers.)
This might be the weakest strawman argument I've ever seen. Well done.
