I don't know why Amazon started to envy our wifi passwords. But the funny things is, they collect wifi passwords even on wifi-only kindles. So you have to connect to wi-fi manually to 'sync your wi-fi password' !
I don't expect Amazon to encrypt these passwords, since they must be decrypted to plain text to be used on our devices. And there will always be a key for that is stored on their 'secure server that employees have no access to' .
The only things I expect is Amazon offering 'Disable Wifi Password' Sync' option in 5.8.2, or the update.bin.tmp.partial trick always working in 5.7.3.
For their awesome data-mining ( and possible data-sharing with gov or trading or leaking ) plan and their delicate double-speak , I felt powerless. But I am still glad to mail
jeffbezos@amazon.com as I may buy 'a PW4 or KT3 shipping with 5.9.x.

Isn't it so ridiculous that a bookseller is asking for my wi-fi password?
