Algorithms don’t close 57 Million dollar advertising accounts without some oversight.

Not even “move fast and break things” evolved algorithms?

(I suspect you are right though, and this is more likely to be a “hot or not” type arbitrary decision from a management team developed around superficial face value judgements and zero empathy... Apple ended up with a “Jobs culture”, Facebook reflects Zuckerberg...)

That is pure speculation. Algorithms are all completely individual and a catch all term for basically anything done in software automatically. Whether the algorithm factors in advertising dollars or not is a complete unknown.
