They only do this ruse for a while, then after controlling a good chunk of the business they “sell” their services officially to the restaurant, including commission. It’s not a charity.
But it's up to the individual restaurants to agree to this. There's no automatic 30% commission. If a delivery company wants to burn their capital offering discounts, why stop them? The restaurant is under no obligation to sign a contract taking on the burden of kreping those discounts.
Very naive view. They will be “strongly incentivized” to sign once the company can threaten to pull their listing off and vanish 50% of their customer base. Nothing new here, standard growth playbook.
