Why does it need these permissions for Twitter oauth?

Read Tweets from your timeline. See who you follow.

Because the OAuth flow for "Sign In with Twitter" only has two permission levels to the account: read or write.

There is nothing more granular like "read only e-mail address and name". They're requesting the minimum possible access to your account already.
