Piracy has become slightly more difficult, mostly because of the difficulty finding good torrent sites.
I've set up Prowlarr with the recommended torrent sites and have found two torrents (h264 with 4 seeds and h265 with 9 seeds at 1080p, or h264 with 3 seeds at 480p) for your query; it took me no more than five seconds. A torrent client isn't enough these days, unless you like wasting your time on Google, but there are technical solutions for that!
Combine this with Sonarr and you can simply add "the climb". It'll download all the episodes for you, and optionally start downloading new ones once the next season comes out.
I can't find where I would watch this show legally. The local copyright lobby has set up a nice website where you can look up legal sources for TV shows, but it doesn't even list the show, let alone show the normal "not available right now" message. With legal-ish access to Amazon, Disney+, HBO, and Netflix through my accounts or those of friends, I'd expect to find it somewhere but I'm not going to bother manually searching through all that.
There's an opportunity for media companies to take Sonarr and make a version that just redirects you to the services you're already subscribed to. They'll have to find some data source for situations like "season 1 is on Netflix, season 2-4 are on Amazon, season 3-5 are on Disney and the specials are on Paramount+" but the industry have done that to itself so it may as well fix it.
Piracy is still often the easy way out for me now that I have the *darr collection set up. There was a short time where practically every streaming show was on Netflix and piracy was the stupid, difficult way to watch shows, and I actually kind of liked it. Then the industry had to fuck it up for itself by splitting off in a million different subscription services.
Hell, nontechnical people still resort to piracy despite their inability to use torrents. For many, 123-super-movie.entertainmenttonite365.biz or whatever you call it is good enough. These websites, seemingly designed as a benchmark for adblockers, are hard to find or navigate but are still considered better alternatives than the restrictive, annoying, often expensive streaming services.
My theory is that that's for one simple reason: you can find a link on Google and just start watching. No need to open seven different apps and do the search over and over again, waiting several seconds for animations and sign-ins.
Some people may do it purely because they don't have the money to spend 20 dollars on watching two episodes of a show, but the same was once true of music and Spotify mostly fixed the music streaming market for consumers, and youtube caters to the rest. Even the people using weird streaming sites don't download mp3s anymore!
