The copyright license is very broad with almost no limitations, which goes beyond the requirements to run the service. It includes right for Twitter to license to others (“sublicense”).

Critical changes to the terms with little users' involvement

Twitter can change the terms at any time when they see fit. They give notification, in their sole disretion, via an @Twitter update or via email. In September 2009, Twitter considerably changed the terms for the copyright license and only gave a very short notice, only a few hours before the changes applied.

Twitter does not require cookies to function

Twitter is transparent about using session cookies and persistant cookies. But Twitter does not require cookies for most of the service to function. Remember that cookies are files on your computer: you can control and disable them.

Twitter deletes your account 30 days after you delete your account. It keeps the rights on your content.

Even if you deactive your account or if your account is closed, Twitter still has all the rights on your Content (the copyright license survives termination). However, after 30 days Twitter begins to delete your account.

Twitter deletes, obfuscates, or aggregates your browsing data after no longer than 30 days

Per Twitter's terms: "We determine what content you might enjoy based on a number of factors. If you have the Track where you see Twitter content across the web setting enabled in your Personalization and data settings, we may consider your visits to other websites that integrate Twitter content (such as embedded timelines). For example, if you regularly visit birdwatching websites, we might suggest accounts that frequently Tweet about that topic, or show you ads for binoculars or birdfeeders. To protect your privacy, we never associate this web browsing history with your name, email address, phone number, or Twitter handle, and we delete, obfuscate, or aggregate it after no longer than 30 days."
