Scale is a huge factor. It makes the most sense to invest in precision ag tech when you have enough acres that the investment pays off. At 5000+ acres, farms are using integrated systems that combine satellite data, on-tractor sensors, soil sensors, drone sensors, in-field weather sensors, with a lot of science to squeeze the most out of the land. At that scale, there's a lot of money invested in a season and you aren't looking for a DIY project, you need production quality product with proven scientific rigor. You probably don't have the manpower to do a DIY project anyway, you are relying heavily on automation and outsourcing. And at the low end, it it more effort to implement any of this than you'll get out of it.

So a DIY solution is aiming for somewhere in the center of the market -- enough scale that it makes sense to bother, but not enough enough money to avoid the headache of DIY. It might make sense for some mid-sized farms in developing economies, but it seems to be a narrow window to me.
