That is objectively false. itch.io's final score calculation takes into account the number of ratings and the median number of ratings from the submissions. If your submission got less ratings than the median, your final score is less than the raw score, which is done to prevent rating manipulation. "Score is adjusted from raw score by the median number of ratings per game in the jam." You can even verify this by looking at the results.
Edit: I've said this before, but I did not care at all about winning. I just wanted to make my game idea and have people play it. Hopefully they would enjoy it, but at the very least I wanted to get some feedback. I could then take that external feedback as well as my personal learnings into future projects. My main point is that everyone should at least be supportive enough of their fellow submitters by playing their game.
