This is certainly not the case in other product areas and for specifically for something that uses the Google name.
If I was expected to go through a full IARC committee in order to get my little Discord bot open sourced under my own account, something that uses the Google name would likely have to get IARC + Legal approvals, along with a proper launch/privacy review.
The OP also notes that they had a competing product in the process of development when they "launched" theirs, likely leading to significant internal confusion, and is something that would've been caught during a review.
I'm gunna be real, this whole thing smells of "I'm purposely bit telling the whole truth" and looks like clout chasing.
