Because 75% of people who voted for Mask aren't active Quest participants and just voted for the sake of it, while 75% of active quest participants weren't Mask voters and would rather play literally anything else!
Masked received 50 Votes, of which I can see 40 in preview; Angel 45, of which I can see the same amount.
Last Update, the following individuals voted:
Wolfy LaughsinLurking Naan GoldExRoot DirtyBean, Red Radio, Zampano, WHISPER, _brightwing, Me, Pseudopod, TheyWhoWatch, and Brainypicker.
Of which Masked received visible votes from:
LaughsinLurking, Naan, GoldExRoot, Zampano, _Brightwing, and Pseudopod.
and Angel received visible votes from:
Whisper_, TheyWhoWatch, Me (but I also voted for Mask.)
So, your statement is not merely wrong, but actively the opposite of correct. Even given
as many non-visible Angel voters as possible are from the 13 thus-measured active people and not a Masked voter, you can only argue at most 46% of voters weren't Mask voters and would rather play literally anything else.
It is true that, by this measurement, at least 74% of Mask Voters aren't active quest participants(merely due to voting base size). But
92% of visible Angel voters aren't active quest participants either! Masked is,
as one might expect of the winning option, more supported by the currently active voters.
