> Does Steam take a cut for in game purchases?

Yes. That's why they cut out remote control purchasing feature from their iOS app, to avoid hypocrisy charges and to avoid the sticky situation where a steam app tried the same (letting you make microtransaction purchases by remoting in to your phone or something).

Same as why Epic dropped their marketplace cut down from 30% something like one week before their "30% is unfair" press campaign which in turn was used to take the spotlight off criticism of Fortnite's release on Android as a timed exclusive with Samsung's new flagship.
