OSI’s license might not be copyleft per se, but it does in fact limit what the redistribution license can do, and requires the source to stay “open”.
Please stop spreading misinformation.
It is not a condition of OSI approval for a license to require that downstream projects be reciprocally open source. You can absolutely take MIT licensed code and put it in Microsoft Windows or some closed source app, for example.
If you're unclear or have questions about something, then it's fine to say so and ask questions in the appropriate forum. What you're doing, though—which involves saying something and then waiting for someone to challenge or correct you—is harmful and contributes to even more outlandish and untrue beliefs about open source than what already exist.
To reiterate: the clauses you're quoting do not mean what you are interpreting them to mean, and claiming otherwise, especially so confidently, is actively harmful.
