Why they don't just make purchases on iPhones 30% more expensive?

They do, but they want their users to explicitly know that those 30% are going to Apple.

  Do they? According to the screenshots in the article they don't. It seems that whoever is actually selling something via Facebook will simply get less from Apple users.

Note that for parity you need to boost prices by about 43%: (100% + 43%) × (100% − 30%) ≅ 100%. (I love sevenths in decimal. One seventh is 0.1̅4̅2̅8̅5̅7̅, two sevenths 0.2̅8̅5̅7̅1̅4̅, three sevenths 0.4̅2̅8̅5̅7̅1̅, &c. Just remember 7 × 2 = 14, 14 × 2 = 28, 28 × 2 = 56 and change the six to a seven for some reason and start again with that, and rotate the whole lot as necessary. It’s just beautiful.)

  I can't help but ask followup questions about what you're saying re: the 7's. Firstly, why are your numbers wearing hats? (I know it represents a repeating number, but how do you type numbers with hats? I assume you're not copy-pasting 5̅7̅1̅ whenever you want to write it out. Is there a shorthand on MacOS?) Regarding the 7's, I don't understand the pattern from 0.142857 to 0.285714 to 0.428571. Are you saying that 0.428571 is easy to remember, somehow? Or derivable from 0.285714? In fact, did you write out these numbers without using a calculator? I see what you're saying with 7 x 2 = 14, x 2 = 28, x 2 = 56. And I see that if you change 56 to 57, then yes indeed it does match the ending of 0.1̅4̅2̅8̅5̅7̅, and then you can repeat the pattern of 7 x 2 = 14, which matches the ending of your 0.2̅8̅5̅7̅1̅4̅ number. But what's the connection to 0.4̅2̅8̅5̅7̅1̅? It's unclear how to use your trick to go from 7̅1̅4̅ to 5̅7̅1̅. Or even why that's helpful in general, or what the overall connection is between all of these seemingly unrelated things. Thanks for sharing!

    What I am seeing is the numbers 142857 in that order. Then for the 1/7, you grab the lowest number in that series and rotate the number until it is at front: 1 is the lowest, so it is 142857. for 2/7, take the second lowest number (2), and rotate it to the front: 285714 for 3/7, third lowest (4): 428571 for 4/7 it then becomes 571428 and so on This seems to hold up with my calculator. Pretty cool. The 7x2, 14x2, 28x2 is jus a trick for remembering what these numbers are and their order. (142856, +1).

    I used U+0305 COMBINING OVERLINE to get the line above the digits. I don’t use it at all often, so I had to look it up (I know its name but not its number) and typed it out with my Compose key (using WinCompose since I’m on Windows): `Compose u 3 0 5 Enter`. Since I do do this just occasionally, I’ve just set up `Compose ^ _` for it, by placing this line in my ~/.XCompose: <Multi_key> <asciicircum> <underscore> : "̅" U0305 # COMBINING OVERLINE The digits in multiples of sevenths are always the same six digits in order, recurring: 1, 4, 2, 8, 5, 7; it’s just a question of which digit you start from. For one seventh, start with the one (0.14285714285714…); for two, the two (0.285714285714…); three, the four (0.428571428…); four, the five; five, the seven; six, the eight.

That's against the Apple store rules as well.
