Well typically people give tips under the understanding that they are supplementing the worker’s income, rather than the company’s bottom line

I mean obviously it should be. This is bananas.

Some states have a minimum wage for tipped employees; where Washington only has a flat minimum wage for both tipped and untipped workers.

If I give you a tip surely it should benefit you. In this case the tip soley benefits instacart.

In many states you only have to pay the difference between the "tipped minimum wage" and the actual minimum wage if the employee didn't make enough tips to cover the difference.
