Marketing sites are usually short-lived. They can die with the platform and it's fine. The OP is building their product on top of Next and was asking about lock-in. I work with React codebases that are 8+ years old. Luckily no-one chose sth like Next so there is a flurry of additional libs, some fell out of fashion today but none of them prevented the app to evolve or be deployed wherever. There is so much money in Vercel that I don't expect Next to die anytime soon but if sth more cool appears people on Next will have hard time migrating. Where someone sticking to more vanilla React can even easily switch to Solid or another non-React jsx solution.
