There's nothing wrong with making cool woven textiles. I suspect if someone had a problem with your comment, it's because it sounds like you're workshopping a startup idea. I get that this is a very startuppy place, but even other startup founders probably get exhausted by all the business ideas shared on this website. (As the saying goes, ideas are cheap and execution is what matters)

I'm not saying you did anything wrong. Just sharing why I think your comment was downvoted.
