The fact that this particular contract involves Uber and drivers and an arbitration clause is irrelevant to the larger idea that contracts are indeed enforceable. That shouldn't really be news.
It's a small difference but it matters. The power difference is a separate issue between employers and employees is a separate (important) issue, though.
The de facto effect is the same except in the rare case where a court sees the wording of the first kind of contract and dismisses the case on its own initiative, since otherwise the arbitration clause would only be enforced on the motion of a party, without which the right would be waived.
But it's not formalistically wrong to use the verb "force" to describe "exercising a contractual election" as opposed to merely "not waiving a default provision of the contract."
