Surprised and not surprised. There's a lot of devs that know a little SQL, but I think it's different when you're mostly using ORMs to abstract away the DB. For business users, you pull up a GUI like this or the one that comes with the DB and sometimes spend hours writing queries and exploring the schema, so you get used to these kinds of tools... especially if you have to move between several databases. I'm sure plenty of devs, do as well, but probably a smaller proportion. It's a great project though.
I use Datagrip as my primary tool when connecting to DB, but DB Browser is still used several times each month because the simple CSV import, adding index and view data.
I even copy-paste DB Browser in Application folder on Mac, to be able to run 2-3 instances at the same time.
