I don't think it's quite comparable though. This is chopping off companies with essentially no synergies with the core business, which are kept in a single monolithic entity. If anything the association is often negative, with the assumption that the only reason Google owns a business (e.g. Nest, Fiber) is to hoover up people's private information.

Now, there would be insane ways of splitting the company. Say putting building and operating data centers into a separate company from the company using the data centers to run services. Or splitting Android or Chrome into a separate company that'd then be funded by selling the default search engine setting to the highest bidder. If that kind of thing happens, it'd be women and children first into the lifeboats.
