That and Hobby Lobby went to court to fight the Healthcare mandate for employer provided healthcare insurance to cover abortion back when Obamacare was being implemented.
They would never target mooselimbs or islime for obvious reasons.
Certainly Hobby Lobby's unapologetic Christianity made them a target, but IMHO, there's also another psychological layer that's a bit more subtle. Hobby Lobby sells art and craft supplies, paints, brushes, sketchbooks, sewing supplies, fabric, etc. Hobby Lobby exists to serve humanity's God-given creative impulse. The command to, "be fruitful and multiply," is not just about knocking out a bunch of kids, but also about building civilization, art, science, etc. Satanists are about destruction and regression so even without its outspoken Christianity, Hobby Lobby would still have been a suitable target for them.
