You are using content from twitter on your page and then using a script from twitter to format the content, right? You've seeded control on how it's displayed. They changed their mind on how to format the content. You are responsible for your page no one else.
This is kinda like asking someone who just got robbed “Why did you leave your door open? You’re responsible for your home no one else.” That’s true, but it’s still not okay to rob people!
