I think the crux of the issue here is that the recommendation algorithm isn't built to say "find ISIS material and promote it". It says "find content that will generate more engagement for this user". Reddit is in a similar situation -- it promotes what other people upvote. Some submissions will be removed due to their specific content, but nothing is promoted because of it.
This is where Twitter could get into hot water -- if the code that was released is accurate, they were specifically promoting tweets by certain people and with certain content. They can't claim "it's just the algorithm" because their algorithm is intentionally biased based on the content itself.
