You are definitely not bound in the same way as with proprietary software, that is why one is called proprietary and one is called free. But depending on the way the software is released it is true that you may still be bound by some terms.
If it's public domain or a WTFPL license then there are no terms and the binary and source code is 100% free.
If it's a permissive license like MIT then the only condition is you must include the copyright notice in the source code, however this doesn't affect the binary and as the binary is all most users are interested in they are not restricted by this term.
If it's a license such as the GNU GPL then there are two additional conditions: first you cannot restrict other users and second you must provide the source code with the binary.
So as you can see with free software you always own your binary in almost the same way you own a CD or a DVD or a book. I say almost the same way because actually with free software you get an additional freedom that you don't get with the CD/DVD/Book which is you are allowed to share and sell copies of free software.
