2) My inner conspiracy theorist says this is a clever posting from someone internal to Clinkle as a PR stunt.
Came here to say just this. This looks very much like an astro-turfing post.
This part just mentions design, possible parter logos, fonts, facebook like boxes and that they didn't obfuscate code.
A $25m "seed" is generally not a good idea but I think worthwhile giving the benefit of the doubt at this point and waiting to see what and how they roll out.
The Yodlee thing is likely for verifying bank/card accounts, not offering Mint-like services.
Unless they ran the code through an obfuscator or something in the android dev cycle does that automatically (I don't know), you can get the full source with full variable names, more or less. The stock javac compiler doesn't do much in terms of optimization, there are a couple things it does (replaces accesses to 'final static' members with constants for example), most is left to the JIT, bytecode -> source translation is pretty straight forward and you don't lose much.
You can prevent this by obfuscating your code in eclipse with proguard, however most apps are not obfuscated.
It's like IDA but for APKs.
Though it'd also be kind of cool to do the transaction in the hearable range... so your phone playing a merchant could make the same sort of 'honking' as old dial-up modems. Not just a novelty, that'd promote the service to everyone within earshot.
