I sincerely believe that the leadership tried to avoid the ads revenue stream and all the ills that come with it for as long as possible, and searched for a lot of ways out (see things like Reddit Notes in the past). But I don't think I'll work in the social media domain again, because the experience really soured me on the sustainability model as a whole. People are generally unwilling to donate/pay for the content, and it's impossible to operate a site where there's no subscription revenue coming in.
