I have never liked spreaders that move like that, but it's not at all uncommon and Faster is correct. They were designed that way.
Often, spreaders that are attached with a single pin, are a lot tighter at the beginning of their lives and get progressively looser over the years due to the hole around the pin wallowing out and the edges of the spreader getting squished against the spreader bracket. You might be able to stiffen them up a little by removing them and doing some judicial shimming or bushing. I wouldn't spend much time worrying about it though. I have never seen a failure of a rig that I could attribute to pivoting spreaders.
