I'm not sure if Apple pays your sandwiches or what, but it's not hard to imagine a reasonable expectation one could login to an apple-owned web platform to manage their subscription. Not third-party. Apple one. Especially after considering two facts; One - they have that platform via iCloud where you can manage billing and subscription, but apparently not for everything and second which is more important - I got alerted to this after receiving an email from Apple titled "Your Subscription Price Increase" and within that email there was this: "To learn more or cancel, review your subscription." of which latter part is a link which when clicked opens up a page saying you need itunes. itunes which I cannot install on my phone nor computer. No other info. I had to dig and dig through google to find that I could probably call someone at Apple to cancel. If that's not shady, it's at least sloppy.
Yes, of course, any defense of Apple must be due to remuneration. LOL.
It's an oversight, I suppose, but a defensible one. Putting management for subscriptions in the AppleID management area of Settings on Apple devices is an entirely reasonable thing to do. For one thing, it means you don't have to futz with a login to get to it.
I'd never use a web login for this. I'm sure most Apple users feel the same. And you have to have an Apple device to consume the subscription the OP is talking about, so ... yeah, seems like a chintzy thing to whine about.
Which was my original point: it's HN, so there must be Apple-bashing. QED.
It's HN so there must be closed source and walled garden simping to no end because no actual hacker has been in these parts for half a decade, all having left after the great walled garden simpfest of 2018.
