The cited source - a socialist magazine that got started with features on Castro, Mao, and Guevara - may, perhaps, be slightly biased in its interpretative lens.
Objectivity in journalism is awareness of biases, not a lack of them.
An example of poor objectivity is corporate media not disclosing that they don't report potentially damaging information about companies because they share parent companies, the owning and operating families are closely tied with the outlets, or they share members across boards.
Another example would be showing that they're perfectly capable of critical reporting of a presidency but not applying that neutrality to all presidencies.
