Well that's kind of the thing, that's why Google announces they are ending those things. Most companies just end development silently and let those things differ l drift off without support or intention to solve issues which becomes incredibly telling for anyone who comes along and decides to integrate that software into their systems or daily life which later just becomes a massive problem down the line.

Announcing the end of something, and even coming up with a solution for it like domains switching to square space, GPM transferring user songs into YouTube music, and SketchUp selling to Trimble are low or even zero hassle solutions that result in longer term support for their users without throwing a "sorry it's all broken now, go fuck yourself" methodology
