'mobile platform' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?

'traditional philosopher embracing online' is the wordplay.
'traditional' becomes 'trad' (abbreviation - especially in music 'trad jazz').
'philosopher' becomes 'mill' (I've seen this before).
'embracing' indicates putting letters inside.
'online' becomes 'e' (as in e-mail or e-commerce).
'trad'+'mill'='tradmill'
'tradmill' enclosing 'e' is 'TREADMILL'.
