While the portable CD players from Sony were branded "Discman", they later used the "Walkman" brand for a range of featurephones (e.g. https://en.wikipedia.org/wiki/Sony_Ericsson_W580i) explicitly designed as music players. So you could actually say that the _iPhone_ ultimately beat the Walkman...

How I loved these feature phones. Did everything I needed, playing music later even e-mail also it was nowhere near as nice as Gmail. Youtube wasn't an option, but the sound quality was at least on par with my Pixel 2. Also phones were small enough to fit in every pocket.

They almost certainly did that just to keep the trademark active.
