Nintendo has increasingly become a problem over the last decade
Of the other related videos, one by Knowledge Husk (7FWyhlS3kvc) points to the CEOs being an issue and that they just had one (1) good CEO: Satoru Iwata (particularly because he was a computer scientist who was pro-consumer).
Now I doubt Nintendo was fully non-evil in 2002-2015 (considering Nintendo actions with 2010s-era Youtube) but I'm sure it was probably the better side of Nintendo.
Nintendo.
Not just crushing fan games, but also issues with the Smash bros community, pricing and availability, eshops shutting down (+needing to buy those games again on new consoles or it's not even available at start), stick drift, fan content policy, also Youtube strikes/claims (both newer for specific reasons and an entire era for let's plays in general). 20 years of content removed from Gmod.
And no this isn't about Japanese law, they choose to be this way.

It is a free and easy way to experience 75% of the experience without even downloading it (data bloat has massively ballooned too, perhaps needlessly in some cases). Also linear stories, or procedural things not being as deep as they seem.
Even when it comes to indie-appearing stuff I often don't like the direction of the game design/difficulty, so it will likely be a more enjoyable experience in those cases too. The narrator also cuts boring bits or issues, also may do things I would not especially when it comes to skill or knowledge of said game. They may do silly things or tell a story. This may be 300% experience (of a new mix).
EDIT: Also never really been into the idea of multiplayer games, competitive or cooperative for different reasons. So watching is a new avenue for that.
