Regardless of if you get 4 months notice or 1 year notice you still have to do the work to migrate and you're still stuck with the sunk cost of investing in/learning a doomed platform.

That's why I wouldn't build a business on Google, because they have a long history of killing things when they aren't wildly profitable/successful. A $10m/yr profit product is considered a distraction of valuable engineer time unless it has some ulterior goal for the company.

And I'm not saying they should change -- they do what'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/yr to billions.

But they can't have their cake and eat it.
