It's an interesting dark pattern...
I understand when products are compared directly: Uber vs. Lyft, Uber Eats vs. Grubhub, etc. Often consumers are looking at the exact same product and purely deciding based on price. I can see what a company would add that dark pattern to squeeze every dollar they can get.
AirBnb, Turo? I don't get it, are folks comparing the purchases directly to "other" products?
