Those connectors are very good. The KELI connectors are very good also.

Silver does not prevent corrosion. In fact the silver surface is fairly reactive and can corrode fairly rapidly depending on the number of silver atoms on the surface that are not fully coordinated. Unlike copper which oxidizes to the +1 oxide (Cu2O) and +2 oxide (CuO), silver does not readily form oxides. Instead silver readily forms a sulfide (Ag2S). Both silver sulfide and the oxides of copper are semiconductors with similar band gaps.
Ah, those darn connectors. Seems there is no perfect solution. Gold and Rhodium don't oxidize, but they are not very good conductors. I had an silver plated AQ rca plug that literally turned black. That can't be good.
Here is another fact to drive ones OCD nuts. Just read how tin plated conductors react with gold. So that is another often ignored no-no.
How about low mass copper to copper treated with ProGold?
In the end, it will be a compromise like most things in life.
Ok, I should have stated that a silver coating will prevent the underlying copper from corroding, but silver itself corrodes. The company you quoted does say they apply an enamel coating over the silver, which would prevent corrosion.
I studied the surface chemistry of silver for several years and I can unequivocally state that silver surfaces corrode fairly rapidly on exposure to the atmosphere. The primary corrosion species on silver are sulfur and sulfur containing compounds. Other corrosion species that I have found on silver surfaces include chlorine (Cl) and carbonates (CO3).
