Do you really believe that? Stuff like that is really troublesome to keep alive. Piratebay is hardly the thing is was, and it's a torrent site, which is relatively easy to host. A better example would be rarbg, which is not alive anymore. They only exist because of almost fanatical dedication of some highly productive individuals, god bless them. Even if they don't get into serious trouble, it's still a hassle to avoid getting into trouble and work with actual content, not just host a bunch of torrent-links other people provide. So, at some point they'll lose the desire to do that, and I am not so sure that there always will be somebody to take post.
In fact, I even worry a bit about what will happen to Linux when Torvalds finally passes away, and for sure Linux depends on him much less so than all those pirate resources on the people who maintain them.
