“A protest group was set up within the community after it was announced that that from sometime in 2006, users will need a Yahoo account to login. Many in the Flick Off group of more than 1,000 have threatened to quit their membership if this happens. It is not what they signed up to, they say. Yahoo bought Flickr in March.”
I came to know Flickr only after they had been acquired by Yahoo!, and thus have always steered as clear from it as I’ve could. Yahoo! has always had such crappy policies in UI design, towards its users and throughout its services that I’ve long since decided to stay as far away from anything Yahoo! related as possible.
