This a huge benefit of federated content. I have never been force-fed content from an AlGoRiThYm that was remotely relevant to my interests.
That said, if someone does successfully develop a bot that does take into consideration my eclectic tastes, it can be easily implemented due to the open nature of ActivityPub. It is unlikely be corrupted by commercial interests to manipulate me, and if it does, I have the ability to ignore it.
