No it can't. I've worked for a bunch of tech companies large and small and interviewed for way more, and I have literally never seen this.
What Apple is alleging is not normal at all, nor is your interview experience. I've literally never even heard of anything like you describe, presenting architecture diagrams of your previous work? That's such a huge red flag, and these companies are opening themselves up to similar lawsuits. The fact that you describe multiple companies requesting this is genuinely shocking to me.
