I'm not sure if the culprit is BERT or using neural ranking. But in the last years I feel that is more common that I leave Google search without useful information. The worse part is that all the competing search engines are using the same algorithms that are only useful for mainstream results.
Google increasingly thinks it knows better than me what I'm looking for.
Or is there some thing that causes Bing to show different results? Perhaps the scammers build a network that targets google because it's bigger?
Memory Hole
"The alteration or outright disappearance of inconvenient or embarrassing documents, photographs, transcripts, or other records, such as from a web site or other archive. Its origin comes from George Orwell's "1984", in which the memory hole was a small incinerator chute used for censoring, (through destroying), things Big Brother deemed necessary to censor."

Tools are not to blame here, it's like blaming the compiler for the behaviour of an application. Starting with the training data and ending with how the model is used in deployment it's the blame of people who made it, not of the neural architecture. The architecture itself can learn anything you throw at it, good or bad.
