Agreed.

For me, one of the least talked about effects is the new incentive for centralization.

With drivechain, miners vote to enable/disable side chains. And, importantly, disabling a side chain unlocks the funds. This creates a new and potentially large incentive for miners to centralize. A 51% attacker can sweep side chains.

Plus, philosophically, it violates the your-keys-your-coins basic contract of Bitcoin. Today, a 51% attacker can rewrite history, but they can’t take coins that belong to you without rewriting all the way back to when you got them. Under drivechain, a 51% attacker can take sidechain locked coin without rewriting history (just by building and mining specific blocks).
