Regardless of if you get 4 months notice or 1 year notice you still have to do the work to migrate and you&#x27;re still stuck with the sunk cost of investing in&#x2F;learning a doomed platform.<p>That&#x27;s why I wouldn&#x27;t build a business on Google, because they have a long history of killing things when they aren&#x27;t wildly profitable&#x2F;successful. A $10m&#x2F;yr profit product is considered a distraction of valuable engineer time unless it has some ulterior goal for the company.<p>And I&#x27;m not saying they should change -- they do what&#x27;s right for them. One engineer working on some distraction project could instead be moved to ads quality and end up making a change worth anywhere from hundreds of millions&#x2F;yr to billions.<p>But they can&#x27;t have their cake and eat it.
