Re: Actually seems reasonable to me
On the other hand, a manufacturer of Frisbees, Skateboards or Bikes has no requirement to pay off any park that might or might not allow the use of those articles. Instead it's the user of those items that have to pay attention to the laws in place, and/or request any exceptions for events etc. that they might want to organize.
Nor are the manufacturers required to modify their equipment with "geofences" that would prevent them being used in certain locations.
In addition, the people using these apps and visiting these parks are almost certainly residents of the areas the parks are in, and therefore paying for these facilities through their taxes.
Augmented reality apps normally require people to walk around looking at a smart-phone, generally no different than anyone else who visits a park these days!
