Both React's and NextJS' marketing is straight-up obnoxious. Currently, React Router is the only React framework that is even offering a solution to data fetching, mutations and transitions in the CSR space. Very basic problems. NextJS is not at all a CSR framework. In that space it suffers all the problems your average CRA application has.
