Usless to download over 300MB

I am President of the local chapter of the EAA (Experimental Aircraft Association). I got an invitation to download a video for a local chapter meeting. After I downloaded MediaFire, and tried to download a video, I received an error message saying that videos over 300 MB one were not allowed. These days, videos are sometimes over 300MB. Why not allow this for an instance where there will be 25 people watching this video?
