Kudos to Niccolò for openly speaking about his mistake of incorrectly stating his video was not sponsored. However I think he made a second mistake which is more serve. As a content creator he must pay more attention to what companies he’s accepting sponsorship from. Given the track record of malibal, this should have been a red flag in the first place.

This is your best option. I did do movie nights with friends during the pandemic in a similar way, but I used OBS Studio to create the stream and Monaserver to stream it to all users. I did not know VLC can handle the streaming to users directly, making this dead simple to setup without additional software. You just need to know how to configure your router to allow the needed port forwarding.

Agreed. From a privacy perspective, it is a lot safer to run the app in an environment where you have admin control. E.g. disable when not in use, block access to sensitive device information, limit background and network activity as much as possible.
