RPi with minidlnad, all devices at home from computers, phones, tablets, video projector, even VR HMD, can play content with e.g VLC.
Very quick to install (basically have a media directory with your videos inside) and still very flexible, e.g new content is added simply by copying from any other device with access, e.g scp which itself can be a script after downloading something.
Thanks for linking to criticism but can you highlight which numbers are off? I can see things about ByteDance, Ant group, Shein but that's irrelevant as it's not about the number of past success, solely about the number of new funded startups. Same as the CEO of ITJUZI sharing his opinion, that's not a number.
Edit: looks totally off, e.g "restaurants, in a single location, such as one city, you could immediately tell that there were large numbers of new companies." as the article is about funding, not a loan from the bank at the corner of the street.
