Answer 1

I think there is value in this kind of question. If we were describing the Internet today to someone who had never heard of it, "Is there $THING on the Internet?" would be a reasonable question. (Can you buy stuff on the Internet? Sure: Amazon, eBay, Etsy, etc...) In our case, the fact that "Is there any decentralized exchanges?" is so frequently asked (here or elsewhere) that it would seem remiss to ignore it.

On StackOverflow, how questions like "Are there any production-grade non-SQL databases in existence?" or "Is there any option other than virtual machines for virtualization" handled? They're a legit question, even if they'd be prone to arguments over details.

Answer 2

I think the behavior should depends on the purpose of the question, if it to promote a product (Spam like) or is it just a help request (noobs are always confused). choosing which tool to use or book to read needs the opinion of the others whom will share their personal experiences ad opinions and like-so anyone reading the answers will discover new solutions.

I think it might be beneficial to answer such question,e.g if by reading such discussion someone discover a tool that he wasn't aware of. However, if the question has an underlying purpose like to promote a special product it should be closed.
