I don't think buying stuff from someone who sells to the public is abusive. I don't think scraping is abusive. I do think workers' rights are important, but the restaurant industry (especially the mon-and-pop end of it) hardly has a great reputation on that front, so I don't think ordering directly rather than DoorDash sends a message there.I guess if that story works for you, you better stick with it as long as you can.
Some software developers it seems go to work each day thinking how can I put other, poorer, people out of work, and erode the pay and conditions of those that I can't?
