There's way more. I'd risk saying google drive has more pirated content today than MegaUpload and Rapidshare combined ever did, just based on the size of the user base and basic knowledge of long tail distribution. Other than that today you have so much piracy on discord, telegram, p2p communities stay strong, and of course the first rule of usenet is you don't mention it.

Probably the largest source of piracy is the widespread normalization of VPNs. Once upon a time VPNs did not advertise so as to not attract IP enforcement attention. They constantly shifted host locations to stay ahead of blocklists. Now VPNs openly advertise on youtube, touting the ability to "access contend not available in your country". That's piracy 101 stuff, at least it used to be. I just watched a youtube by LLT on how to bypass encryption to rip your own Blu-ray disks and upload the resulting files to your plex server. Even talking about such tech was considered criminal only a few years ago. The laws haven't changed. We just now have a generation of adult decision makers who have grown up with piracy as a norm.

P2P is still where you go if you don't want potato quality video.

While having a sabnzbd+*arr setup isn't particularly difficult to a technical person, the general opacity of its underlying workings (NNTP? News articles, providers? Block accounts?) has kept lawyers outside of USENET for decades.
