Do you have a source for this?

Last I checked, the ledger on Bitcoin and Ethereum are functionally identical. A value against a wallet address. There are no "accounts" on either.

Bitcoin and similar chains use a “UTXO” model that tracks outputs of individual transactions, even when made to the same receiving address. This allows for control of specific coins when spending. ETH doesn’t use UTXO and I don’t believe it has the ability to perform coin control.

It's called "coin control". On Ethereum, your entire account balance is inextricably commingled. On Bitcoin, you can maintain the provenance of your coins. https://bitcoin.design/guide/how-it-works/coin-selection/

Here's an article by Vitalik, explaining the differences between UTXOs and Ethereum's account-based model and why Ethereum did it that way.

Because Bitcoin is more flexible than most people think and offers an ever increasing amount of different transaction types, it is important to read it from top to bottom to get a grasp on it.

Many people confuse the account ledger model with "account abstraction".

Ethereum has the first, the second is wip.

Yep. Though here the confusion seems to be regarding Ethereum accounts and "account balance" interface in many Bitcoin wallets.

How did you check? This has never been true. Bitcoin has always used UTXOs.
