That makes sense. FWIW, my opinion is that Ted missed the point by naming "technologists" his enemy.
Technology is just what people do. It's not divorced from nature, or from humanity; it's the process of using nature's laws to make nature more palatable for our existence. Because nature does not care about us and would see humanity extinguished as fast as any other organism in the long history of life on Earth. While Ted found a certain tranquility in the woods, most people find the kind of survival activities he had to undertake to be toil---dull, dangerous, deadly. And not even Ted lived completely off the grid; the oats he sustained himself on came from a farm, and that implies agriculture, transportation, and distribution---roads and fossil fuels. The gun he used to shoot rabbits implies bullet and gunpowder manufacture; he didn't mention it explicitly in the interview, but I don't assume he had his own sulfur and saltpeter sources or was smelting his own bullets. So really, his world is divided into two types of technology: the kind he'll bomb people for using and the kind he's okay with. As you noted, ideological purity is lacking. I think it's lacking because it's basically impossible. People vastly underestimate how much dependence basic quality-of-life has on technology.
Rather than bomb people to stop them from changing the world (which doesn't work), we have to work with people to find how to not use technology in a short-sighted and self-destructive fashion. Without further information, I can't say for certain how the timber roads that so inflamed his rage fit in that story. Probably they aren't worth the cost. But the point is, it's a dynamic process of working with people, generally, to find solutions, and setting yourself at odds with civilized society by bombing it guarantees failure.
We passed the point of no turning back the day we tied a pointy stick to a rock and enhanced our predatory power to take down things that evolved tougher skin and sharper claws than we could kill with our physical traits. The only way forward is through.
