Binaries may contain suspect code regardless of the license. Yet 999 out of 1000 users prefer binaries, because they are not programmers and would have no clue what to do with source code in their hands.
The source (ie. download origin, and PGP signer) of the software is always far more paramount, if you are worrying about bitcoin theft and other abuse.
Binaries compiled from open source code can potentially be confirmed by the community that the binaries are indeed related to a particular svn snapshot of source code. I am not sure how, but I am sure this is possible to confirm.
Binaries compiled from closed source code can not be confirmed by the community that the binaries are indeed related to a particular svn snapshot of source code without modification, because the code has obviously been modified and there is no way to know what the modified code looks like.
