Hide "Sign in to Thundermail" in the menu"

[GAGA]

Thunderbird is one of the best email clients. It is ad-free and privacy-focused. 

However, starting with version 153, there is a "Sign in to Thundermail" option in the menu. I use Thunderbird to handle all my email accounts, including the one provided by my institution. I do not use Thundermail.

I wish there were a way to hide this.

I understand Thunderbird needs some sources of income, and ads from Mozilla might be expected. However, as a promotion (an ad in some sense) by Thunderbird, it should be optional to dismiss or turn off.
