Xcancel was accused of using the twitter API. You don't have to use it. You can have a machine vision model process screenshots. You can also process the Dom. You don't offer a freely usable service or software to the public, only the final result. That final result is opinionated according to the very public accounts you want and does not offer broad scope access to accounts. You do not let the public control it nor provide a product to browse to random or posts about anything like nitter. Or you can process the content into your own news account with ai which is what most news accounts do anyways and then it becomes yours.
