Are you a vegetarian? I am! And as a vegetarian, I can tell you that I love it when restaurants sell Impossible Burgers. First, I don't cook (unless you count making a bowl of cereal cooking), so it's not like I'm going to make it for myself. Second, restaurant dining is about more than just calorie intake - sometimes I want to go to a restaurant, and as a vegetarian I appreciate when they have tasty things for me to eat. Third, if I'm going to a restaurant as part of a larger social gathering, or as a company outing or whatever - in other words, if I'm at a restaurant when I would not have otherwise chosen to (which I'm sure doesn't happen to just me!), then I appreciate it when there are options for me.
I’d add to that: big brands make vegetarianism more palatable to everyone. If I’m stuck ordering a salad at a bad restaurant, I’m more likely to be mocked by meat eaters than if the restaurant sells good burgers (esp in the US). When I was in the states recently and the restaurant had an impossible burger, instead of people saying “why are you vegetarian? Where do you get your protein?” people said “oh, the impossible burger, yeah I tried that recently and really liked it”. It was a very pleasant change.
