The way its used in the article at least, to me means having a view of the world that feels true and important but is bleak and disempowering.

Like the sibling comment said, 'red pill' is seeing the truth of the world (or, what the community that uses the term red pill thinks is the truth at least. often this refers to the truth as decided by internet mysoginiats). Black pill is this truth + its unchangeable and hopeless and pointless and why do anything and oh god I wish I could go back to not knowing.

If its used by somebody reasonable, blackpill is a pejorative with the implication that the ideology is more cynical and hopeless than it really should be and has the connotation that their ideology is a little too internety.
