There are Hacks and Hacks, one can use a specific exploit and cause damage or just gain access to part of a system OR even open pandora's box.

I don't spend time on 'belittling' people, I try to check my understanding of reality by comparing it with others.

EDIT: serious consideration wouldn't relate the two directly, rather indirectly: if someone was hacking HE, why not try to do the same on HIVE while they're at it? Or do you discard that as absurd too?

Hive Engine is not really decentralized, even if it's already open source (besides deployment scripts I'd guess). That means full control over the Main Note, should be close to full control over the running system. Meanwhile, Hive is super decentralized, so if you gain full control over one of the main HIVE Notes, you are still just one of many and can't just change things.
