An attempt was made 3-4 years ago to replace downvotes with personal image hiding; the results were a boatload of pants shat over freedom of speech or whatever and the volunteers running this place just didn't want to deal with all the screaming and whining and insults. Given ==\~recent events\~== I very much doubt that those in the decision making chairs will want to try any changes with the potential to have more shitty-pissies.
As a side note, don't use money or donations, either giving or withholding, as a tool to institute change. I can assure you that it will not only not work.
