Answer: find the email address of the person the product manager of Google Drive reports to, and start sharing stuff with them. (/s: not condoning doxxing here)
LOL, you're assuming anyone gets promoted by fixing issues at Google. Wrong. You build some new shit and switch teams. Someone pitches a new project and builds from scratch. Rinse and repeat. This particular issue happens (at least that's my recollection a few years ago) frequently enough at Google that there were memes about it internally. Not sure giving additional feedback would help.
This is a common narrative about Google. There is some truth to it but the blanket "nobody gives a shit about anything other than launches" claim is bogus.
