I didn't see a specific raise in rejections at Adobe. I can live with the few ones they reject, and the reasons they give me.
And I don't have the feeling they are particularly picky, except for their illustrative editorial content maybe.
I mean: it's illustrative editorial, I get that, but sometimes plain editorals are accepted too while some other illustratives are rejected. Their policy in that regard is not very clear to me, or maybe I'm not fully understanding the concept of illustrative editorial.
