I've considered getting back into it occasionally.
Why: Convenience and access. From having everything on Netflix a decade ago, to now having almost as many subscriptions as I used to have cable channels, it's a pain (let alone a cost) to install dozen apps on my phone tablet TV roku etc. Their quality varies WILDLY. The user experience ranges from pretty decent to seemingly user hostile. I've recently watched a set of seasons of a show pirated a decade ago, then last two seasons on actual subscription service, and it sucked: app would not let me download to SD card, had to take precious phone storage. Subtitles were 2 seconds behind with NO way to adjust. Fast forwarding was wonky and basically unusable. And best of all, it auto deleted itself 48hrs after downloading so I had to keep redownloading same stuff over and over. Brutal!
Why Not: As explained above - It's pricey and time consuming, there's a fair amount of risk in pirating, and technology seems to keep changing. I made a post about that a while ago, but I'm no longer at a point in my life where every 6 months I can spare the time to fully rebuild and reconfigure and troubleshoot a stack from sabnzbd and nsbmatrix to udirwioay and fewiap and fdsjei, and then 6 months later again to fdwjieo and wearp routed through wefheio and zxcnzxcv. I have a friend who keeps urging me to set it up because it's so easy - oblivious that whenever I try to use his helpful "how to", a) It's 3 pages long b) it is missing about 10 pages of details and c) It's already out of date so it's "do that, but none of that actually because these days now the cool thing is ____" :D
