Thats a misleading over simplification. A collision being found implies something different than "its cracked." A weakness that was theorized sometime ago has been demonstrated in practice. Finding collisions and altering files in a useful way to produce a duplicate hash are different things. There are FAR bigger security concerns than this one right now IMHO.

I recall even seeing posts about people claiming this meant original data being reconstructed from the checksum! That would be truly amazing since I could reconstruct a 680MB ISO from just 61d38fad42b4037970338636b5e72e5a. Wow!
