I didn't suggest this was a ploy, I'm confident that the person in question has only the best intentions. I don't think it's unfair to step back and ask what the right approach is, intentions aren't always enough.

For instance, the issue with flammability/melting and also microplastics contamination is real and worth asking. I wonder if using these bricks as building foundations or something might not be a good way of solving both problems at once. However, that's an idea that would only arise if we ask pressing questions in the first place.
