"Algorithmic boosting" is not (always?) the same as an editorial slant. Promoting the post with the longest title would be an "algorithmic boost", but clearly not editorial in any way. The most common forms of algorithms are just a function of the number of times people viewed it weighted against the age of the post; there is still no editorial slant there. Even recommendations algorithms like YouTube are mostly the same, with an additional weight based on how likely others who watched the same things as you were to view that video.
