Full disclosure, I've never asked LF to pay me for my contributions, nor have they offered. None of the people I know who are lk contributors who I've just asked have gotten anything from LF. They have been solicited to pay to attend LF organized conferences.
This comment is useless without knowing what/how many contributions you have made.
They don't pay contributors in a Patreon- or tip4commit-style scheme; they employ certain core developers. If you are not a subsystem maintainer / lieutenant, you're not going to get a job offer from them. (And even if you are you shouldn't expect one.)
"They have been solicited to pay to attend LF organized conferences."
That appears to be a big part of the business model of LF.
