It forces fans who would otherwise disregard it as a noncanon moneygrab to play it, increasing player statistics and potential revenue, so it's a good idea.

Simply put, it doesn't exist to me. I don't care what they do. Maybe I could watch it on youtube or read it on a wiki or something. In the case of the Utawarerumono one I just visit a gallery now and then to see new art.
Which I have now done after forgetting for a few months. I REALLY hate that I can't confident say "Oh that's Character A", because it might be some parallel universe thing or time warp or just a new character that looks extremely similar. Sigh. Gacha garbage.

If I learn that a franchise strongly relies on media that I refuse to engage with, I probably won't engage with the other aspects either. It's discouraging to think that maybe I'll run into a narrative dead end that makes no sense unless I've also subscribed to whatever other service they are using.
It's actually highly ironic that I say this, when I have watched lots of anime adaptations without giving their source material a second glance. Have I learned my lesson or am I just trying to convince myself that I have?

Putting aside the story aspect of it, I'm not a big gacha guy but from what I can tell the franchise spinoff gacha are always among the worst gacha and close down after a year anyway.

If it's connected to the larger narrative then they will give the background information from it that's needed for understanding these things when they create media that I do watch or play.
And to be fair, Gacha games are often the least of such concerns regarding IPs that they often are a part of. I have no idea how many Fate VNs or games there even are and I am not going to read or play them all and I don't care that I am not, I'll just hope that if an anime comes out that references it they will do a good job summarizing the important points in it for me.
