Yes, and that's the main reason I use Plex nowadays. I mostly stopped using it as virtually everything I want to watch is on legal streaming services in the UK. However even when content is available, on some services the UX is so awful I'm driven to download it elsewhere. For example, even though Handmaid's Tale is available on All4 in the UK, their app and player are so awful it was easier to go through the rigmarole of illegal downloads so I can use Plex instead.
