Stock being up 2% today is myopic and meaningless. Look at the performance over the last year. FWIW, Wall St isn't a bunch of morons trying to financially engineer an airplane to take off.
The post seems to misinterpret that Doordash + Grubhub are somehow in cahoots with Google to skim off of restauranteurs. What Doordash & Grubhub are doing is an extreme form of "growth hacking" that doesn't have any considerations for the collateral damage it creates - they should be held accountable for that. Google here is just the provider of a tool that they abuse, they need to work on ensuring that this form of abuse should not be possible.
To deduce that there's a conspiracy between Google + Doordash is taking it a bit too far..
Doordash lists every restaurant they deem worthy of delivery in a particular area - the restaurant doesn't have to be part of a contractual agreement with them. They call this OTT (Over the Top) where the courier orders the food like a normal patron and gets the food to the customer.
In this case, it doesn't really sound like the owner of the restaurant was on the Doordash platform. The blog post doesn't seem to clearly indicate that they do. If they are not, I would think that there is an extremely strong legal case for copyright infringement, especially since Doordash is not even working to generate revenue for the restaurant, but redirecting you to a generic bbq restaurants page.
Your naïveté and misinformed idealism are quite amusing. Uber had to solve huge problems in realtime marketplace management, mapping, transport economics, financial systems, safety and fraud prevention to make the magical experience of pressing a button and getting a ride possible anywhere in the world.
Don't assume you have the answers that a twenty thousand organization couldn't figure out.
