not going to say it is 100% of their time, but they are paid to work on it.
You can see five consortium members on the front page of sqlite, the cost of a consortium membership appears to $75,000/year[1]. That's enough to pay developers.
And that doesn't even include Apple, who I have to believe has a big investment in sqlite, and probably has some form of support arrangement with them.
