"Continued vandalism will not be tolerated." - I see no vandalism here. 
What I do see is 1 particular user hiding behind OSM policy and refusing to engage with a legit discussion around what is or isnt appropriate to be mapped. |

"The easiest solution is for you and others you know that disagree with OpenStreetMap's policy is to boycott products that use OpenStreetMap"

This doesnt solve the underlying problem at all. And I think you know that. 
You think you're providing a public service but are actually doing the opposite. 
When someone hurts themselves on a previously secret trail that riders would find when they were ready, thats on you. When areas and trails get shut down due to injury and overuse, that will be on you.  Jimmy was right, mapping isnt a neutral activity, it has real life consequences that aren't always positive.
