Voting against is a vote for the status quo plan which was to build out own blockchain tailored specifically to our needs. This is very much still possible and doable, however it means there needs to be a much longer "testing" phase, specifically a testnet even after everything is done to properly ensure the security of the over all platforms. Using an existing blockchain can piggy back off the existing security model and the fact that said chain's code has already been audited/well tested.

I'm not sure which meeting it was, but I previously went into detail as to why Ethereum isn't a great choice for this -- or any fee based blockchain. It completely ruins the user experience if to add content to the platform you need to pay to do so. Imagine paying everytime you made a facebook post, or a tweet, or shared something that would be useful to other people (content). This goes in turn as to why DEXs feel bad to use because you lose money in fees simply for using them.
