If we only allowed people to load pfSense on hw that we sell,or have sold, you would have a point.
Since we don't even attempt same, my point stands.
That point no makes sense as this decision cuts out a lot of the cheaper hardware people ran pfSense on previously so when they look at their options now your own lower priced stuff becomes more attractive and oh yes it has AES-NI and is fully compatible.
This really feels like a long con to get people to upgrade their hardware to a pfSense unit.
