Yup - that's the "ink jet printer" marketing style. Get M4 free or cheap, but you'll need to pay to use the way you want.  As a paid member at Daz, I've even noticed a trend to put out new outfits for V4 with 1 mediocre texture & sell for $1.99 on sale, then offer 3 or 4 cooler "texture packs"  for $6-7.  But hey, the fine folks at Daz3D (like me) have rent to pay, gas to put in the car.  V4 (if you have her Morphes) even has a male form, which isn't bad for simple uses.
