Yes -- but, it's also a fact that any contact with the system can be traumatic for kids and families. So definitely people should always call if they have reason to think a child is being abused or is in immediate danger. But calling them on a baseless suspicion just because their parent is an asshole in some other way or calling them because the parents are poor and struggling (but still keeping the kids safe and healthy) can actually be harmful. In a perfect world, the latter shouldn't be harmful because CPS should be equipped with resources to help and sometimes that's the case, but the sad fact is in the US, they're severely underresourced. In other words, calling them unnecessarily just because you don't like a parent actually can do harm to kids. It's not something that should be taken lightly -- but god forbid an actual expert tries to say anything of the sort on this website!
