Coin swap does this:
1. Gives the illusion of progress by the dev team. Draw people in to bet that there's a future so they can sell those stake reward now. Nothing is actually done by the coin swap, the total supply is still the same.
2. Without actually burning any coins (perhaps? It looks like, I'm not so sure. Would like to know what coins and how much was / is / will actually be burned), the only outcome is for kb3 to continue selling lower down to 1 or 0.1 sats per kb3. But without the coin swap, no one is even buying at 0.1 sats.
Unless they can come out and prove to the contrary, this coin swap is unnecessary.
I think. Perhaps they'd be successful in generating some hype and have it rise just a little. But be damn sure that it will go down after that.
