The license only limits you on what you can distribute, nothing else.

You can certainly do that as long as you do not distribute seq with it in
a proprietary blob. What you cannot do is limit what people can do with
seq.

Looking at what it does for the purpose of reverse engineering does not bother me.
You can learn from anything and anybody.
