"First thing I noticed when I did the blast run were those inserts.
Knew they were up to no good and were manmade..."

You didn't know, you suspected, and we are no closer to knowing right now.

Also, I have read opinions of others that the "hiv-ebola" insert is not at all uncommon in other sources of natural genetic material -- even plant viruses -- presumably including the cleavage site.

Professional opinion.

I will say no more.

It’s a sequence motif thing. Not just a sequence homology thing.

For something to insert not only a sequence homology but also the precise motif is very unlikely.
