OSS license obligations mostly kick in upon distribution, hence this is a pivotal concept in this context. It’s also important because of the language in the TOS that says the code won’t be used outside the service. The stuff related to streaming is kind of unrelated here because movies aren’t under copyleft licenses and so the question of whether or not there was distribution there is not relevant- the question is whether or not the copyright holder’s monopoly right were violated and those include the right of public performance, public display, as well as distribution. They would have violated other copyright rights even without a finding of distribution.
