"Do we include ads?"
"Sell telemetry data?"
"Try to force users to use our browser/search engine to generate ad impressions?"
"Should we just make the whole thing free?"
Personally, I wish they'd just make home editions free as in beer, make it up by charging businesses the CAL bullshit and office/o365 licenses. They need to develop and support those things anyways, home user revenue must be a drop in the bucket compared to Azure/O365. Especially since OEM PC/laptop purchases generate even less revenue for the Windows license included.
Doing so would also make sure your user base is familiar with using Windows on their home devices and carry that over to business use cases. Otherwise tablets not running Windows will continue to eat their lunch.
