Eli5 Why does it matter what temperature the water is when we do laundry?

I’ve been a “throw everything in and wash on cold” person forever, but I started to notice certain things such as towels that typically require hot or warm water didn’t feel right anymore. Once I switched back they came out feeling soft and fluffy as usual. Why does it matter?

Grease hardens in cold temperature and loosens at warm ones. While detergents have actions in them that partially makes water temperature irrelevant, I can’t imagine it doesn’t help to have 30-40 degree Celsius water when washing a shirt covered in cooking oil.
