Uber and Doordash are both examples of abusing workers and their resources to externalize costs on the worker.

What about people who have been out of work for a year and all they can do right now is deliver for Uber and Doordash so they can make rent and put some food on the table?

Is it ideal working conditions? No, but its better than nothing, you can set your own hours, and you can leave when the next opportunity comes.
