I mean, they could also say "Epic is just trash compared to Spotify as far as value to have on your platform goes" and I couldn't really fault them for that.
I don't think it causes issues for them specifically though. I bet they offered Epic deals, Epic just didn't want them. If anything they could point to a few recipients of such deals and go "But look, we're doing this, we just won't do a deal with Tim Sweeney because well, who in their right mind would?".
I can now only laugh about their past statements of "uwu we are losing dominance as the market leader because we can't compete with apple music on iOS, because they can offer the service for less money uwu"
All while no other service is able to compete with them on android because of their special deal lmao
