To be clear, our projects (at Parse.ly) don't have anything to do with Tor. In fact, I didn't know much about Tor until researching DARPA and the other participants involved in the program. But, I'll address your general question, which is, do I have a moral/ethical problem with DARPA funding some of our open source work, such as streamparse and pykafka? The answer is a resounding "no". There are very few funding sources for open source work. Part of DARPA's funding supports fundamental tech advancements (famously, the Internet itself and GPS) and recently, important open source projects (such as, Apache Spark and the Julia language). Now, there is no doubt in my mind that open source software is used for intelligence purposes, regardless of its funding source. To restrict ones contribution to F/OSS based on the fear that some government or entity may use it toward an end you disagree with seems a battle you can only win through willful ignorance. The nature of open source software is that people can use it however they please (within legal limits, of course). This is a trade-off I accept with eyes wide open, and in my mind, the benefit to the community for F/OSS always wins out.
