Is Blockchain-com's default account custodial or self-custodial?

Hi, I tried to figure out that, yet I am still confused even after reading all the articles.

Different scenarios:

1. You register now on Blockchain-com App, without submitting ID.
2. You register now on their official website, without submitting ID.
3. You registered in 2019 on their official website to generate Bitcoin addresses, without submitting ID.
4. You registered in 2013 on their official website to generate Bitcoin addresses,, without submitting ID.

They changed from Blockchain-info to Blockchain-com, how does that affect the custodial or self-custodial accounts?

They changed the name from "seed phrase" to "recovery phrase", how does that affect the custodial or self-custodial accounts?

If the default account is custodial, then it would be very misleading to call it "secret private key recovery phrase".

It seems that if you register on their APP now, the default account will be a custodial account called "blockchain.com account". There is also a self-custodial account called "De-Fi account"(not the default account).

Do you know when did Blockchain-com introduced the custodial account as default account?

Thank you.
