It feels to me like you‘re saddling the horse from behind.
Most companies will not be okay with someone using their stuff, especially not if the person or company makes any money with it.
Instead, I would ask in what cases you dont have the company find out about it. Like, if you share movies, shows, etc. Do so in a country that doesnt comply with takedown requests etc.
But yes, you should rely on open source stuff as much as possible.
