From what I have seen, there are really only a relatively small number of colleges like that. Some of those are quite popular colleges in certain circles, but many colleges that are not at the top of those popularity charts simply do not get enough yield out of EA applicants to “fill up” their class.
I note all this is distinct from rolling admissions. Rolling admissions obviously isn’t about a point in time but it can have a similar effect at a selective college, and that again is true at certain popular rolling admissions colleges.
Restricted majors are also an entirely different subject. If a major is restricted it is then very likely to be a good idea to apply early, whether through EA or rolling, if possible.
