That seems scary to me, because even if it normally works, if it fails, it's presumably not something customer service can "make ok" especially because they aren't charging you commissions and you are, as they say, the product not the customer.

At this point, customer service of the major discount broker I've used for many years is so abysmal that the last thing I want is a free alternative that promises to do more for me. It makes me think of how impossible it is to deal with Google when something goes wrong with their free offerings.

I think social media has become a societal problem because there is so much revenue available from exploiting addictive behavior, and the logic has to lead to brokers trying to catch up. If you are sensible with investing, the system doesn't need or want you.
