This is not what article says. Previously they wanted to spin off Alibaba stack but because of tax issues now they will spin off other stuff. Either way, results would have been exactly same: Partition of company in to two. There is zero talks of selling of core business. In fact article clearly says that "activists" investors wanted that but didn't got it. Board says they are 100% behind Mayer and Mayer says she is deeply committed to running Yahoo. In fact she is taking only limited leave for maternity. I highly doubt you actually read article or may be you are just jumping to conclusions but without disclosure that this are your interpretation, not the actual content of the article.
