It’s sort of irrelevant for the University of Maryland. They don’t claim to meet full financial need, so it doesn’t really matter if their admissions process is need-blind or not. There would be no point to it. They can admit a student with need but offer skimpy aid — because they have no policy to meet full need. Most of the aid you’d get from U of M would be federal aid (Pell grant if you qualify, and federal loans and work study). It’s at their discretion whether they’ll provide a university grant.
In any case, if you need the aid to attend the school, what would be the point of not applying for it?
In general, need-blindness (or lack thereof) really only matters for schools that give robust financial aid, promising to meet the full financial need of every enrolled student. Those colleges are working with a budget of X dollars to distribute, and they have to fulfill their promise. Most of those schools have to manage their financial aid budget by managing who they admit. Among those that meet full financial need, all but the very richest colleges have to look at the amount of need their applicants have.
