> I do have some concerns that tor is a tool that needs to be improved upon greatly to truly accomplish its goals but I am not aware of any projects that are doing so. Re metadata, fingerprinting, developers inserting backdoors etc. I always try to tell people about Tor's limitations, which are considerable. (I wrote the content for the EFF graphic that was linked above, and one goal was to show people things that aren't hidden by Tor — for example you can see an NSA agent in the graphic performing some kind of correlation attack between source and destination by monitoring the network at multiple points. Of course, the source of data for this doesn't have to be fiber optic taps, so other entities that can get source and destination data can correlate them too.) Tor is doing work on all of the things that you mention: metadata, fingerprinting, and developers inserting backdoors. One could wish for more work and that it had happened longer ago, but all of those are active areas of concern and research for the Tor project.
