Why should Stake reward it's customers when there are maintenance? The maintenance is done to improve the long-term experience of the user. (reducing errors / improving security / reducing lag etc.)
Will your Bank give you a bonus into your Bank account when their systems are down for maintenance? It is inevitable that sites will go down, once in a while, so we should not demand something when that happens.

I find this same issue across all crypto gaming. Casinos in real life and services in real life charge you for everything. Maintenance (my bank charges me maintenance fee can you believe it). Fees just to keep an account when they should be paying US for our money.
But crypto casinos give faucets, loyalty rewards giveaways etc. And people complain here the most.
Every sportsbook I play at users come whining for "lost opportunity" during maintenance. So weird:)
