There has never been a restriction in watching movies online but the only condition or restriction is to do it the legal and right way. What does this mean? It is generally said that a movie or an audio of a newly released movie is to be watched in the theatres promoting the crew of the movie who would have spent all their efforts and time in the massive making of the movie. But nowadays every new movie has a copy online. generally, before the release of a movie all the online websites are all blocked in order to make people compulsorily watch them in theatres. This is more for movies that have some very famous celebrity and that has been given a great hype.
Even with such strict restrictions, some movies get leaked and come to the internet world because of some miscreants. It is for this reason that we say that watching movies online and that too a new movie as illegal. But none of the websites stop people from watching old movies and listen to songs online. In fact, here internet plays the important role of entertaining people with their likes and favorites. People are also allowed to upload and post videos and songs. I usually purchase 10000 views + 1000 likes here for all the postings made. This is because I try posting some common interests of people, not necessarily movies or songs but also information and also some important social videos that might help people in some way, might create awareness or something that is very informative.
The Internet is good and instrumental in spreading useful information only until it is used within the limits. Of course, it does not stop you from using any of the restricted websites but it is us, as human beings, who should know to differentiate between what is right and what is wrong.
