I do think this is something that Google could be smarter about mitigating. In the longer term picture, higher conversion rates advertisers will spend more on Google AdWords budgets, so an ad that drives right to the restaurant people wanted should be a net win. I think the larger problem here is that DoorDash & GrubHub are better positioned to pay a higher customer acquisition cost (better capitalized, higher margin businesses long term, and also more drive to create brand awareness in this moment), since they can convert for people who want alternatives to whatever they searched for, and on top of that they can more easily justify investing in tuning their marketing campaigns. So from Google's perspective, it may be hard to perceive a strategic advantage of fixing this. What is surprising to me is that investing in tuning their marketing campaigns hasn't resulted in developing custom landing pages for those campaigns that, for example, might put people on a page for the restaurant in question (maybe with a sidebar for "looking for alternatives?"). That'd no doubt improve effective CPA for their campaigns.
