I've seen this happen with multiple groups from various companies.
It's not like other groups have control over what they get versus others. Dragging other groups is just toxic.
Also, the money the company gets isn't earmarked for specific groups. It's not that group's money. Other groups aren't "leeching". That's not how companies work. And again, it's not the other groups fault if the company spends money on them.
Any anger should be directed at the company not other groups.
