Unless there's some conversation not shown here, it reads to me like they are using "garbage" to refer to random contents of people's messages and/or posts (and saying that the whitepaper is not garbage, as opposed to random messages and posts, which are not "useful" on chain). I don't think they meant to call your project garbage, just that it adds garbage to the chain.

It's been an on-going conversation that's been going on a few days.

Huh?! No one controls the blockchain.
