How is it a win for Google to release something open-source that had potentially cost them lots of money? Even if they don't need and pursue it anymore, why would they just give it to the competition?
It's always easily said to "just open-source" it but Google is a business and owes outside software developers nothing.
How can another company compete with a product Google no longer offers? There is no competition because Google quit competing.
If Google spins up a project and then abandons it, how could they possibly be harmed by someone else offering a comparable product? Google has already accepted a total loss on the product, there's really nothing for them to lose here.
> What benefit do they see in exchange for the effort in open sourcing things?
Goodwill and more people willing to try whatever they release next, rather than the current situation of “Oh, Google is releasing a new thing? Pass. They’ll just stop supporting it and I’ll be left in the cold anyway, so no bother even trying”.
Killing so many projects makes fewer people interested in trying whatever they release next, which means fewer users, which means a higher likelihood it’ll be abandoned. It’s a vicious cycle that could be stopped or even reversed if they open-sourced their abandoned stuff.
To be clear, I’m not necessarily advocating Google should do it or that it’s be a clear win with no downsides. Maybe the upside wouldn’t be worth it, but there is an upside.
