Then you make burgers hip again. You extend the menu. You bring out cool new styles. You advertise hard. You give samples, you discount, you run specials, you collab with others. 100 things you can do to reinvigorate your 'boring Burger' business.

You don't just pivot to copycat the tacos business years late. Why would customers go to you rather than staying with their Taco brand of choice?

I believe the real world analogy would be that McDonalds started using real beef and chicken in their food, expanded out the breakfast menu hours. Which they did, deciding whether it strengthened their future prospects is an exercise best left up to each individual.

You laugh, but there are still franchisee owned stores selling McPizza and *the horror, the horror* McSalads.

Your analogy doesn't work because people /do/ like Tacos, and people /do/ like Facebook to not be TikTok. The proof is in the active users. Silicon Valley is such a self important circle jerk. You can operate a business, it lose users, and still exist. Christ.
