It sounds to me like something that's quite dangerious. Maybe it helps people with narcolepsy but maybe it will be another thing people abuse like amphetamines?
Do people drinking coffee in the morning *abuse* it?

I remember there being kind of a burst of articles about it on HN about ten or fifteen years ago, with a lot of commenters talking about their use of it.
Textbook case of "how do we select the most number of people who would say yes" ism. People who are taking modafinil and have a strong opinion about it.
If I'm a student I would never click on that ad in the first place if I have never heard of modafinil (like most people haven't), because the survey is about something I don't know. And if I vaguely heard of it and click, there's a friendly awareness page and quiz right at the start about the thing and its side effects that says I won't get paid if I don't answer correctly, what are the chances I'll continue wasting my time?
Same people who use adderall for work.
That'd be either exceedingly rare or borderline unwise.
I'd love to see some actual forums or papers about that because this seems very unusual given the partly overlapping effect but significantly different paths.
Whatever is available currently.
"People who use adderall for work" is a generalization, for example stock traders at Wall Street are famous for doing cocaine, taking amphetamines for work and possibly every smart drug, including modafinil.
But they won't take them all at the same time because then they get too high to work.
Modafinil is extremely easy and cheap to get for anyone with one eye and one working finger, Adderall a tiny bit harder but easy for a "trader".
"Possibly every smart drug, including modafinil" is just many guesses mixed up, nothing to actually discuss with. I'll stop wasting electrons here, you do you.
