A family member of mine has an Apple phone, and the lack of availability of not just open source software but even freeware or freemium software astounds me. They make it so difficult to distribute anything, that it's not worth it unless you are getting significant revenue. This means that often the only option is something extremely scammy that charges monthly for the most trivial capabilities.

Of course, Apple gets a 30% cut in any scams, so they have absolutely no incentive to do anything about it, and really their policies are what create it, in the first place.
