RSUs tend to be considered lower risk to employees. For instance if you were issued options last year when stripe was valued at double what it is now, there is a good chance your options are underwater.

With RSUs while the value has gone down, they are at least worth something, if you could sell them.

Also, Stripe was in hiring competition with companies who used RSU compensation as a major component of total comp. This allowed them to more easily do an apples to apples comparison.
