For me the wording isn´t the issue. It is the intention and the shape of what is behind this wording.
Yes, on the paper the instrument works and there is no need to buy the full product. correct.
But due to the very limited fetureset the usecase accordingly is extremly limted aswell.
Hence imho it is telling me to buy the product to actually be able to use it.
And this is against (what I personally think) what PB is about.
This is my personal opinion and I am in no way speaking for anyone else or in the name of PB.
With the Kawai Felt and the MVP/AIR there has not been and still is not any intention and
suggestion behind the contribution to (make me) buy the consecutive product.
