There are many bloggers creating fear and try to help to promote sales of VPN for some commissions. So read these articles with a pinch of salt.
I am not encouraging watching unauthorized contents, but so far none in singapore is fined by court for watching unauthorized contents online. In other words, it is not illegal to watch online video even it is not authorized from the rights owner.
However, it is certain that authority will punish those who host illegal contents and using it to make money.
If you think that certain apps or website are hosting unauthorized contents, and it is not right to view them, just don't view it. It is bad to use VPN to mask your identity. Something like wearing a mask to rob a bank, knowing that it is wrong but try to hide identity when doing so.
If certain apps or website are hosting contents and you think that it is not illegal to view it, just do so without the need for VPN.
Take an example of youtube, anyone can upload video to youtube, and some of them are unauthorized, you may or may not know whether it is authorized.
The exception is bit-torrent. For bit torrent, every receiving node is also a host, i.e. when you are downloading video file or watching online video via bit torrent, you are actually hosting the illegal contents.
