why not?  explaining your tech to prospective customers is good PR,
and I would be surprised if your competitors don't already know it all.
this is why Intel and AMD routinely disclose quite a few details of their
respective microarchitectures.

suggesting that your competitors are stupid or ignorant is _not_ good PR.
