The article headline is wildly misleading, bordering on being just a straight up lie.
Google didn't ban the developer for reporting the material, they didn't even know he reported it, because he did so anonymously, and to a child protection org, not Google.
Google's automatic tools, correctly, flagged the CSAM when he unzipped the data and subsequently nuked his account.
Google's only failure here was to not unban on his first or second appeal. And whilst that is absolutely a big failure on Google's part, I find it very understandable that the appeals team generally speaking won't accept "I didn't know the folder I uploaded contained CSAM" as a valid ban appeal reason.
It's also kind of insane how this article somehow makes a bigger deal out of this devolper being temporarily banned by Google, than it does of the fact that hundreds of CSAM images were freely available online and openly sharable by anyone, and to anyone, for god knows how long.
They didn't get mad, they didn't even know THAT he reported it, and they have no reason or incentive to swipe it under the rug, because they have no connection to the data set. Did you even read my comment ?
I hate Alphabet as much as the next person, but this feels like you're just trying to find any excuse to hate on them, even if it's basically a made up reason.
