You could just stop being so damaging to the mtb community and leave your hobby to the communities that want your efforts? 

You've considered that your and OSM’s blanket belief in mapping what exists on the ground lacks nuance when dealing with sensitive land use, right?

Land ownership and rights: Many unauthorized trails are built on private land, First Nations territory, or in protected areas without permission. Mapping them potentially implicates OSM contributors in violating property rights.

Conservation efforts: Trails in ecologically sensitive zones are often kept unpublicized to prevent erosion, habitat disruption, and overuse. Publishing their location undermines efforts by local stewards, conservation groups, and land managers.

By mapping a trail that is officially closed, unsanctioned, or dangerous, yu may unintentionally encourage use exposing themselves, the project, or others to liability in the case of injury or damage.

Mapping isn’t ethically neutral. It has real-world consequences and pretending otherwise is dangerous.

Trail builds often explicitly ask for trails to be kept off Strava etc, what gives you any right to ignore them to publicize what they've built? Especially if trails have been build with low user numbers in mind. 

In my opinion, mapping “what is on the ground” without local input is a form of digital overreach. It gives users a superiority complex but does nothing to benefit the users of the trail systems in mind. 

You've clearly had this discussion before, so I fully expect it to fall on deaf ears. But to repeat, your online actives are harmful to the local people that enjoy these trails and mapping them conveys to benefit to anyone other than yourself.
