I mean, you say its "absolutely not true" and yet that's literally verbatim from their Brokerage Account Agreement.

Maybe in some cases they go above and beyond their account agreement if they like you as a customer, but according to the agreement you sign with them its not their problem if things go bad in this way.

On the flip side, clients have no guarantee that there would have been a counterparty for their order.
The reason nobody will be compensated here is due to two things,
(1) There is no way to determine what a fair execution would have been, since clients couldn't submit orders in the first place.
(2) Clients will adversely select their losing trades for corrections and this would bankrupt Robinhood in about five minutes.
