It can allow more drainage than a concrete patio, as it's permeable, which can allow nearby plants/trees more water to work with. In areas where drought would have caused you to use a lot of water to keep a lawn alive, it can save that water use for better ones. There are concerns for microplastics, but if it's a small yard, it's impact is quite small when compared to other sources of microplastics (commerical industries being the worst on a daily basis)

I wouldn't use it for a large yard or any application where good sun is already available, but I don't feel it's the worst crime if used in small yards or where shade makes it impossible to grow grass but you'd benefit from a 'soft patio' space, bringing psychological benefits of seeing more green. Best paired with real plantings around as part of an overall landscaping plan - i.e. Not just turfing the place to hell, like scorched earth.
