I can't read the article, but you define "monthly active users" as a user exiting the platform i.e. pulling their money out?!
Originally, I had assumed it was "users who don't open the app/website" but expectation difference caused me to look it up:
> Robinhood defines a monthly active user as a "unique user who makes a debit card transaction, or who transitions between two different screens on a mobile device or loads a page in a web browser while logged into their account, at any point during the relevant month. A user need not satisfy these conditions on a recurring monthly basis or have a Funded Account to be included in MAU." [0]
I have a Vanguard, I haven't opened it in a month. By the above MAU definition, Vanguard lost me too.
Again, this _alone_ doesn't tell us that RH is doing poorly vs other Retail Brokers. They could be, but not enough info.
My take is - most people don't want to see their ultra red portfolio and are just not opening the app.
