Hey just a heads up, you added an extra "to become" in your title. Anyway great question, I've always wondered this, hopefully someone knows better.
Perhaps the growth of everyone placing files on clouds these days may be contribute to its inpopularity, or simply because the name just got lumped together with copyright infringement.
Thanks and yes I'm comfortable with English as my first language. I was trying to post my comment with respect for OP. A QWERTY keyboard has the U and I together, my phone keyboard sucks for sure.
