I often use cotton/poly blends in quilts, I just try to have the cotton at least 60 to 70%. I don't get pilling, nor have problems with the other issues mentioned.
As to the why, I ask why not? Many of us quilt and live on a very tight budget and make use of what is available within our budget. I am a frequent shopper of thrift stores in linens and clothing looking for usable fabrics. I check the labels for fiber content but I do not automatically eliminate anything with poly in it.
The most important factor to me is the hand of the fabric. There are some 100% cottons out there that I wouldn't buy!
Hugs and smiles!!!
