eToro holding cash in QMMFs, what are the benefits?

When I logged into my eToro account, I received the following message:

They ask my consent to deposit my money into money market funds. This is a practice many brokers do to earn money on uninvested cash. What I donโ€™t like here is that there is no compensation for the user, or at least itโ€™s not clear to me.

Iโ€™d feel it more fair if eToro would share the interest earned on these assets with their users. Iโ€™ve just contacted them to clarify if such an option is available.

Let me know your thoughts.
