why should it be?
ahh whaaat? mashes downvote button
since you are still reading, what is the exact thought process here, can you articulate this? So the service works and still provides a convenience for you, but is this action being masqueraded as the most effective way to get the company to change a policy amongst all other possible actions? Is it just to not "support" a company that does a single thing you disagree with? Is it something else?
I think there are more effective ways of bringing Instacart into compliance with your ideals. Isn't that a possibility?
edit: and no responses by time of writing while on the way to getting downvote censored. Be interesting to see if it flips when a different crowd gets off of work.
