That's very surprising. I would have thought that would be the first avenue of attack for adblockers.
Also, who wants to help me retrofit this thing to actually block ads?
How do you know what the development environment 'felt' like? Are you Roger Dingledine or Nick Mathewson?
And I doubt that you will find any evidence that it was used before being made public. Using TOR before it was public would be like screaming, "HEY I'M HIDING SOMETHING! AND I'M US MILITARY OR INTELLIGENCE!". The whole point of releasing it was to gather a userbase. Otherwise, TOR wouldn't be very anonymous at all.
For example, lets say you want to throw off Google's targeted advertising algorithm. Let's pretend you want to buy a stapler. Right now, if you go visit a bunch of sites that sell staplers, or a stapler manufacturer, then you'll probably start getting ads for staplers. In order to counter this, you could visit a bunch of random sites while mixing your stapler research in. This way, it's difficult to spot the trend.
This is a gross simplification, because a smart algorithm is going to see that you've visited a bunch of random, non-correlated sites, and eight stapler websites. So the noise that you're hiding in needs to be specifically crafted. For example, you still want to do stapler research. But you know now that you need to be even sneakier. So you visit twenty sites on subject a, twenty on b, etc, then you do all of your stapler research in a single 'window', and then continue onto more random subjects. Thus it's more difficult to figure what you were actually researching. You could probably write a script to do this pretty easily.
I'd like to tack onto number 3 though: 3a) Don't try to learn everything. Being a jack of all trades and a master of none isn't the solution. Be able to write good code / thoroughly utilize the technologies and frameworks that you DO know. Then progress from there.
TOR is still a valid tool. No, it wasn't designed to foil NSA level surveillance, because it was built by the US. But this vulnerability isn't even related to TOR, it has to do with the TOR Browser.
The Snowden leaks contain slides where the NSA clearly laments the use of TOR, so saying that it never has been trustworthy is simply not true.
Other than that, your explainations are clear and concise, which is rare for this topic.
