A quote from the comments on the question
@MikeW this is not off topic. The google-cloud-storage tag is officially supported by Google.
This is a funny thing about tags, especially sponsored tags. They give off a certainly feel for official support, when they are in fact nothing more than owner sponsored advertisements, however the user than made this comment obviously thinks otherwise. Just putting a logo on a tag doesn't automatically make any question about that tag on-topic.
Google also sponsors the android tag. Does that mean we have to accept any android question? This is somewhat rhetorical, as Google has openly embraced Stack Overflow as an alternate source for programming questions with Android, but never tried to redirect support to Stack Overflow. Now, as halfer points out, the android tag is somewhat of a mess, but that's not Google's fault.
So to answer your question, no. Stack Overflow is not a replacement for any company's normal support. It is here for on-topic programming questions about the company's product(s), but support questions have always been better suited for the company's own support channels.
To see what happens when this doesn't happen properly, do some research into the facebook.stackoverflow.com experiment. In the end, Facebook never really made the distinction properly and ended up sending a lot of unprepared users here that asked random facebook questions that were downvoted into oblivion and closed. Meta also saw a lot of other questions, including a lot of admin type stuff and rants about app developers. Somehow the users that where sent here believe we were an official support channel for Facebook.
In the end, this looks like a support question to me and is better directed to Google. I have voted to close as such.
