Interlaced video files should no longer exist.

Seriously, fk interlaced video.

> upscaling algorithms can invent information that doesn’t exist in the image

That's not a falsehood. Upscaling does invent information that doesn't exist in the image.

"Information" in the information theory sense. The output of a deterministic upscaling algorithm can be exactly described by the input and the algorithm. There's no added information, only a different way of presenting the original information.

Yes, they should, as should silent movies, black and white movies, old game consoles with exotic output formats like vector graphics, and the like.

It is a worthy endeavor to create and maintain video playback software that lets people consume beloved content that was made to the technology of its day, including home videos, sports games, TV shows with special effects edited in 60i, and video games.

Perhaps that author was being pendantic, but from an information theroetic perspective it is correct that you cannot invent information with upscaling.

The upscaled image does not have more information than what was in the original image; you can reconstruct the upscaled image given only the information available in the original image, the output resolution dimensions, and upscaling algorithm.

That's like saying fractal images are not information. Just because something is generated by a formula, doesn't mean it's not new information.
