Have a read of how Fetal Bovine Serum is produced.
This isn't really fair, there's plenty of ways to make it without fetal bovine serum.
I'm in the process of writing an article that will hopefully look into this in more detail, but from my experience working in a cultivated meat company currently, there are no alternatives that work as well as fbs. There is a company that has received around 15m usd of funding and we've tested their serum replacement, and it just doesn't work very well. So we are still using fbs. In certain applications, the concentration has to be as high as 20% in the media. Fortunately for their conscience, I don't think the scientists know the details of it's production, if they did, some would probably not come in to work anymore.

Did they just stop using their own product or what?
Nope, but I get the feeling I'm not gonna like it
A cow foetus is removed from it's slaughtered mother, then it's heart is punctured with a large needle and all of it's blood is sucked out.
