More often than not, Twitter has opted for common sense over high handedness.
Last time over, they surprised the world with Innovator’s Patent Agreement, where they totally redefined the solution for on-going patent wars.
According IPA, the inventor (not only Twitter) holds the patent and Twitter can sue someone only with consent of the inventor. Contrast this with Oracle suing Google over Java IPs given the fact James Gosling, creator of Java, is now with Google.

Few days back, Twitter came up with its usage policies, showing clear intent to encourage user to interact with more Twitter users (as opposed to Facebook, which uses extreme steps of banning to ensure you interact only with people you know in real life, or can convince FB that you know them).

One of the changes is to strengthen the “Discover” feature. Twitter will now suggest you friends based not only on data available on Twitter, but also on sites which have Twitter plug-in. This would include all the blogs you often visit. This tracking of personal data is widely used by Google, which shows ads based on content in your mails (creepy!). Flipkart which suggests you items based on the pages you visited (not so creepy, but you don’t want to keep foot prints of your window shopping right?).

What separates Twitter is that it provides the right to deny tracking.
They call it as Do Not Track. This is similar to much popular Do Not Call Registry.

Twitter has documented how to enable do not track for various browsers in this support article.

Surely, it does not benefit Twitter in anyway, other than posing a challenge to its developers on complicated algorithms. However, it ensures that the user is still in control of his data.
To me, a company which can care about users’ issues, often wins the race.
