A system like robinhood can have hundreds of moving parts, if 99 of them are horizontally scalable but 1 is not, eventually that 1 piece will become the bottle neck, and the fact it hadn't been made horizontally scalable yet is more likely to be a testament to how much work would have to go into doing so.

This is an unfortunate viewpoint. How quickly did we forget that robinhood is literally providing a service that no other company was able to do before. You want 100% uptime, you won't find it in an online service, let alone an online fee free service, you'll find it on the floor of the exchange.
$0 commissions aren't a big deal either. If you just buy and hold, it makes no difference. If you trade actively then a real broker with better tech and order management is worth way more than the fees.
Haha, true. Call up you AWS account representative and you may find that certain service limits can’t be increased for love or money.

Provision the resources and take the financial hit in costs.
If your architecture wasn't able to scale horizontally because it was poorly designed, heads should roll. This isn't some social network - these are financial platforms where literally the individual customer is financially dependent.
Heads. Should. Roll. Tell us the post-mortems, and then tell us who got the boot. Completely unacceptable.
