I was all in on the ecosystem when I was a few years younger, than I started to care about privacy, and although Apple might be good compared to it’s direct competitors, I don’t trust mega corps with all my data, nor do I support that tendency.
Also, I think it is good to not be too deep in their applications as a lot is proprietary and when you’d decide to move, they can’t be exported and used between services.
I still use their devices (phone + laptop), as I find it hard to change them, even if I think Android looks better these days (I don’t want to switch to Google services for example and with LineageOS I can’t use key applications), yet I use a minimal amount if their services (Apple Music (TV is included in a student offer), iTunes to buy movies. But stay away from iCloud in favour for open source alternatives and flexibility.
