The change happened early in 2004 when Orlik took over production. Perique was expensive so they cheaped out. In the Spring of that year, I bought a pound from Synjeco. The blend was all Virginia and Brazilian lights.! I was surprised when I saw it. I complained, and they offered to take it back, but I would have had to pay the freight back to Switzerland, so I kept it and mixed it with perique. When I wanted to try it again in 2005, they promised me that it a VaPer, so I bought a pound. They lied. Kentucky (not dark fired) was substituted for perique in approximately the same amount the perique had been. It wasn’t bad, but not what I ordered. I jarred it, came back to it a few years later, and it was fantastic, but it wasn’t the same as what I spent years smoking.
I tried it again in 2011. It was still a Va/Kentucky blend. That’s the formula MacBaren licensed when they took over production, and under the rules of the contract, they cannot alter the recipe, even though MacBaren is using their own source tobacco instead of the previous sourced varietals.
As for keeping the name, it is marketing. It's also a contractual obligation.
