MS used to have this trust problem too (remember windows 8?), but they’ve turned it around. I’m happy to use VSCode because I’m sure it will exist many years in the future. If there were a GoogleCode, would anybody use it, or would it be DOA for the same reasons as Stadia?
There was Google Code, a service that was similar to GitHub. Google Code was closed down on January 15, 2016 (source: https://en.wikipedia.org/w/index.php?title=Google_Developers...).
Google did at least one attempt of creating an IDE (I can not judge from the outside, though, how serious this attempt was): Google Collide
YouTube video: https://www.youtube.com/watch?v=8Gq12bLbm54 (jump to 1:45 to see it in action).
Well, Google open-sourced it in 2012 (i.e. shot it down): https://www.wired.com/2012/07/google-open-sources/
A fork of Google Collide on GitHub (its last commit was from end of 2018, though): https://github.com/WeTheInternet/collide
Many of my friends and colleagues were so hyped about it that I kept reading about Stadia just to understand what I'm missing.
(well, it turns out I didn't miss anything)
Really? All I remember is huge amounts of skepticism that Google would really commit to it, and as we know in the end they didn't.
