I know it's mainly because she's the protagonist.
But I think the fact that we've seen Marinette suffer multiple panic attacks, breakdowns, and nearly spill the beans to Adrien multiple times... And we've never seen Felix suffer any guilt, and even outright screamed at Adrien over information he's deliberately leaving him in the dark over speaks volumes.
Marinette sees Adrien as his own person. Felix sees Adrien as his cousin and, therefore, one of his possessions.
And yet the fandom acts like Marinette is scum of the earth and praises Felix nonstop. It's insane.
