So two questions:
a) what do those "up to 3%" consists of and depend on exactly?
b) Why not put up this information for everyone to see? You can put the "YMMV if with another company" up no problem.

We found that more confusion was caused by listing it on the general website (payoneer.com) with the disclaimer than not listing it. Some companies prefer to subsidize certain costs like card activation, maintenance, while others do not charge for loading of the card, etc. When you see the fees on the actual application, those are always correct and specific to your situation.
The link you posted, for example, shows fees when you apply for the card directly from Payoneer.
The "up to 3%" refers to foreign transactions. In other words, transactions made in a foreign currency (non-USD) or cross border transactions. This is something that exists in all credit/debits cards, and is not specific to Payoneer.
If you have any additional questions about the fee structure, please let me know. We try to be as transparent as possible with the costs of our service, to avoid any confusion. We strongly believe that our service satisfies a very real need in today's market, and that our pricing is highly competitive.
