Assuming this is a non-issue like you say, I still don’t see why that makes this a problem?

It is actually problematic to spend time, effort, and other people’s attention and understanding making weird defensive claims to non issues.

Why? This makes it seem like we can only concentrate on one issue at a time and that by making biodegradable blades we’re somehow stopping something more ‘worthwhile’ from happening? We can do multiple things at once. Even if this makes only a minor difference, I still don’t see why that’s a bad thing? Surely any attempt to improve things is a good thing, no?
