Only in the very early days of the web, were links standardized around blue/purple text, and even linked images had blue/purple borders.

But quickly web designers decided that the conventions were boring or ugly, and changed the default color schemes and removed underlines and borders. The web as a whole began moving towards CSS and JavaScript and more full-fledged web applications.

Putting the disappearance of purple links on cloud companies and Facebook and Google is rather preposterous.
