This is no different from ETH, Lido staking has ~30% market share[0].

Stake centralizing != less security. no amount of stake can allow validators to steal your funds, this affects only censorship resistance. So actual validator count is more important than superminority.

In case of USDC I'm assuming Circle should be running their own validator, which is the source of truth.

As someone who has used most networks, Solana has the best experience for transacting USDC.
