Finally(!) it came to me, just over an hour ago. I drew this. I give you *drum roll* the Inclusion-Exclusion Map for design.
#misusability #designethics #inclusivedesign

Simplified example using Twitter as the service:
1) EXCLUDED. People with certain disabilities (why are image descriptions not default?)
2) UNWANTED. Bots, haters, misogynists. Underage children.
3) People with disabilities are finding ways to bypass poor design.
4) Bots, haters, misogynists are still very much active.
5) INCLUDED as target group are WEIRD (western, educated, industrialized, rich...)
6) Meanwhile, many women - who are still INCLUDED - are being harassed, because (4).
7) Many participants are not mapped at all.
