Never played "in the bush" and never been hassled for airsoft guns. Generally try to stay away from bush games. Organized tend to be better.
Back to FT's orginal point, this is corporate trying to say "We support the 'sport'" and impressing to people how much they care about safety. You know who else cares about safety? Suzy Soccr Mom, when lil Timmy asks for an airsoft gun for Christmas. When she does her online research (read: googles airsoft) and comes across those Facebook posts, guess who she thinks is all about the safety.
This is PR101. Get in front of a problem before it becomes a problem, so when lil Johnny gets shot by a cop that sees GUN and lil Johnny has his orange tip painted or a Gemtech suppressor on it, it's more likely that a law saying that you must keep the orange tip will come down, rather than one that puts restricts on airsoft guns in general.
Echo1 probably doesn't care if you paint the tip. Pretty sure it's good for them, since it voids whatever warranty there is on the gun.better for them.
TL;DR: Echo1 don't care. Echo1 don't give a fuck.
