Kamino blocks users from refinancing through Jupiter Lend, causing controversy

According to The Defiant, the Solana lending protocol Kamino has faced criticism for preventing users from transferring loans through Jupiter Lend's refinancing tool. Kamino manually blacklisted the on-chain address of Jupiter Lend's newly launched Refinance tool, blocking users from closing positions through that address.
Jupiter core contributor Kash Dhanda expressed dissatisfaction about this on X. Fluid co-founder Samyak Jain pointed out that Kamino directly added a check mechanism to lock users out, preventing them from moving to platforms with higher yields.
According to DefiLlama data, the total locked value in the Solana lending market is approximately $3.7 billion, with Kamino holding over 60% market share, but its TVL has dropped from $3.71 billion at the beginning of October to $2.33 billion currently, a decline of nearly 30% in two months. As of the time of publication, neither party has publicly responded to the matter.
