As the title says, what are the risks, I assume people don’t host these servers for no reason. Is it just the ad revenue they get from the popups when trying to start the movie.
Could they be running exploits on here that would make it not safe at all to do so?
True, that is a thing to consider. I have to use an iPhone because I get it through my place of employment, and if I had a nickel for every time the actual OS postponed an automatic update because I wasn’t connected to power / I seemed busy / the stars just weren’t aligned properly, I would probably have over a dollar.
In that respect, I like my desktop (Debian) so much better: I can set it to update the OS automatically, which includes all installed software (as long as it’s installed through the official repository), and it will let me know if something failed to upgrade, so I can do it by hand. Also, they rock at getting critical security updates out in a timely manner. I’m not sure how much I trust Apple with that.
