And who stands to lose the most if people don't feel incentivised to write original and quality science posts?,
If Steemit is not successful then those with the largest stake will lose the most. I can't be responsible for the actions of every significant stakeholder, but I do try my best to personally vote for what I feel are high-quality posts, encourage and assist others in doing so, and downvote low-quality posts (including the above).
What may be difficult to accept is that a decentralized system has no authority that can step in and dictate that posts such as the above will never get upvoted. We can only hope that over time incentives cause a shift (though sometimes a slow shift) toward better outcomes.
