It's a bit like the famous HN post where somebody said that Dropbox is not needed if you have rsync and friends.
Technically this can even be correct. You can build and operate a good, secure solution for yourself if you have time and skill to build. Could make sense for a company handling sensitive data. Would hardly make sense for most individuals who are not professional SREs / SWEs. (To check how it feels, an engineer can try to sew themself a pair of pants to wear daily, or do something similarly mundane in what they are not skilled.)
A solution that can reliably work for non-experts is very important.
Sure but in this case most of the difficulties are artificially imposed by Apple, depending on how the tribunal responds to their alleged iCloud monopoly it could become as simple as choosing a compatible provider and putting your username/password in.
