There is some kind of confusion of ideas going on here, and maybe it's one of the keys to understanding resistance.
If the assumption is that having the source available means that some other binary with the same name and unknown modifications will be floating around, I'd say its as much wishful thinking as it is simply unlikely. Assuming that you are even distributing binaries yourself, you, as the creator tend to be the most trusted source for them, and as a result, searches for the product nearly always land your page/distribution point first
And yes, you can always protect your trademark per the Mozilla/Iceweasel example. Open source/free software license violators tend to get called out pretty hard.
