Maybe the business shouldn't stay afloat, maybe it should wind itself down.
I say this as someone who was approached by InstallMonetizer in 2011/2012 to add IM to the installers of my Windows apps. I declined, of course, because I wouldn't want to trick my customers with the tactics that InstallMonetizer uses. Tricking customers with EULA-like 'offer screens' to install browser toolbars is wrong.
I would rather close down my business than treat my customers that way.
