Huh I never type in portrait if I can help it, my thumbs are way too big for it. Landscape any time I’m typing and even then I wish I could make the keyboard bigger without losing visibility to what I’m typing/replying to. I also don’t swipe type, have never really liked it.
It doesn’t really matter what they call it. Companies that want to be waterfall (or more accurately, whose executives want waterfall style commitments) are going to be waterfall even if they call it Scrum.
