And I can vouch that fruit teas aren't at all nice and they leave a weird color as an after thought in your mug. Not a nice look. And the fruit taste isn't too nice towards the end of your mug. So no. I'm not an advocate of fruit teas.
Earl Grey tea was made specially for the 2nd Early Grey who was Prime Minister of United Kingdom from 1830-1834. He also abolished slavery and reformed child labour laws.
