Not only is it a year without revenue... I imagine this will devastate their revenues in future years as existing customers up for renewal during that time will likely permanently migrate to another CA.
It looks like Mozilla and Google have created a set of circumstances where the rational next step would be to wind down WoSign/Startcom and just start a new company.
Which would require creating new roots to be submitted to Mozilla's CA program, and passing the bar for inclusion of a new CA.
That's a multi-year process, unless they can get another CA to cross-sign their root, like LE did. I doubt other CAs will be willing to carry that level of risk given the reputation of WoSign/StartCom.
