Makes me wonder if that is part of the problem. If you have to put some of your own BTC on the line and since a large amount of the funds for their coordinator did come from Wasabi themselves if they found themselves in a financial hole. And as much as we would like to think we are all good people and would donate to the cause we know that is not the case. Not defending what they did, just putting it out there to think about.
IMO if the problem is
only money, they could increase coordinator fee or launch aggressive donation campaign.
o_e_l_e_o mentioned that it's a problem of not enough outputs, but this can be solved by forking Wasabi Wallet, getting enough developers and contributors behind it, change its name, branding and website, and launch an aggressive advertising campaign to get Wasabi users to switch to a
truly private wallet.Then the problem would be reduced to a purely funding one as you have described.
