What is Reddit's opinion of Sync for iCloud?

From 3.5 billion Reddit comments

I've only bought music from Amazon, but what am I missing here? If you have a Windows or Mac computer, you can access iTunes and download your albums, which are DRM-free, and then you can copy them to any device or storage you want.

So if you switch away from the Apple ecosystem, do one-time transfer and then buy new music from Google Play or whatever else? This assumes of course that you have a computer running either Windows or MacOS. Which is...pretty likely.

Also, there is an Apple Music app for Android, but I'm not sure what that gets you because I don't use Apple Music.

EDIT: Of course your other points about imessages and icloud in general are true. It's not like you lose your iCloud account when you switch away from iOS, but there's no official Android app for accessing your data. There are unofficial ones like this but I don't consider that a real option since I'm not too keen on giving my login and password to random free apps on the Play store. They're making money somehow.

Yes, it's my company's shared iCloud calendar for my team, and it's a private calendar, so I can't get a public read-only link.
But I've solved my issue. I've used this app on my Android phone, and I've set it up manually on my laptop (with Kalendar) with an app password generated on my Apple account, and with the https://pxx-caldav.icloud.com/xxx link I found.

I used this for a few years and couldn't complain, but it has some... quirks. It can and will cut calendar alerts until you locate and disable the setting. Other apps I tried included the reminders from icloud, but caused wakelocks.

It takes some setup to use, but yes... Yes they can https://play.google.com/store/apps/details?id=com.granita.caldavsync&hl=en

Not out of the box, I don't think. How about https://play.google.com/store/apps/details?id=com.granita.caldavsync&hl=en_GB&gl=US ?
