You’re right about the classic games like NES, SNES etc., but I know for one that they took down Super Mario Bros. 35 permanently which is a part of the NSO subscription.
I do think there should be more easy official wireless options, but it isn’t actually difficult to transfer your screenshots & video’s over to a PC. All you need to do is put your microSD card in an SD card adapter, and plug it into a PC. Although that worked better back in 2017 when it released; most computers don’t have SD card slots anymore.
I used the Facebook posting feature back in 2018 before I had an SD card because I was running out of space. I regret it now though because it severely compressed the video & audio and entirely wiped the date/time metadata. Even though I don’t recommend it, I feel that Facebook would be a better option than Twitter, because you can private posts.
I’m not disagreeing with you, but this video style is only meant to discuss the issue, not simply tell people exactly what’s happening and end it at that. But I see your point, and I’ve noted it: I’ll make sure I share more quick and to-the-point video’s when I do in the future.
