A rather simple utility that for some reason requires a login, I see no value in that when there are so many analogs that don't.
Back in my teens I was really wanting to get into 3D animation and virtualdub was one of the first tools I used to create reels since the free modeling and rigging tool I used at the time didn’t have any editing capabilities.
But let's not pretend it's about that...they just want you data.
