Classes like this are nothing new. I dislike unethical long shots the same as a 100 yard gut shot by a guy that hasn't held his rifle since last season. If they are truly marketing from the 1000-yard kill angle, shame on them. What I see on the link is not that.
"Our precision hunting series is designed for hunters who want to show up to season sharper, steadier, and more prepared when the opportunity finally comes."
"Learn the essentials of long-range marksmanship from the ground up. From rifle setup and ballistic data to field mechanics and positional shooting, this course builds the foundation for confident, ethical shots in the field."
I think practice and instruction from skilled shooters would benefit just about any hunter. In the end the decision to take the shot falls on the individual. Training in "real world" environments is quite eye opening for many and could serve as more of a reason not to take the shot.
