記錄一下有這個現象，在 Hacker News 上看到的「Cleaning up my 200GB iCloud with some JavaScript (andykong.org)」，原文是「iCloud Cleanup」。
裡面提到 iCloud Photos 無法依照大小排序的問題，所以自己寫了一段 js code 解決。
想要記錄的是這段，文章後段有提到空間計算很不準確的問題：
So iCloud says the video is 128MB, I download it and the video is actually 48MB, and my free storage increases by ~170MB when I deleted it. Interesting!
以及發現愈舊的檔案吃的空間愈多，甚至到七倍：
It's weird that my storage freed up more than 7x the removed files size, and weirder still that old, big videos appear to have a much larger storage footprint in iCloud than in real life.
這不知道後續會不會跑出訴訟案？
