In a March 26th, 2019, email from Google’s Paul Gennai to Atul Kumar (bolding mine):

In terms of the Samsung proposal, a few thoughts:

I realize that Jim noted a $50M a year number, but it’d be helpful to put that into perspective. What would that be in terms rev-share number, recognizing we might prefer to hide it in some way?

Note that I do think that a rev-share would be better at disincentivizing other app stores from being preloaded (given it’d defray revenues), which is why I liked the idea of offering a rev-share across Search and Play, but not breaking out the figures in our accounting to them.

I’m confused on the homescreen exclusivity part. If they’re distributing via Play, is the fight to have them remove Galaxy Store from the homescreen really worth fighting? I can see them digging in here and I’m not sure it’s worth us being tied to it.

Google did wind up doing the revenue sharing arrangements with RSA 3.0. Wouldn’t companies have to factor in this lost revenue share before preloading another store? asked Epic. “Yes, another app store would have to compete on a similar basis,” said Gennai.

We’re going to lunch now.
