I get the argument, but email is also very different to the kind of open-web network that the fediverse resides in. There are problems the fediverse faces which email doesn’t like discoverability. The emails either come to you or they don’t. With federated social media, you have to find the content you’re looking for first. Maybe you use a search engine, or somebody gives you a business card with their handle and instance, whatever. Then you have to figure out how to view those posts from your home instance if you want to actually interact in any way. There’s browser extensions and stuff which try to make this easier, but that’s another thing that has to be explained and set up, plus not everyone is visiting from a web browser with extension support, or a web browser at all for that matter.
It’s not fundamentally impossible to understand the fediverse, but there’s more of a barrier than email, which can be explained in a single sentence like “Your email provider gives you a unique address that anybody else can send emails to and vice versa.” I don’t think convincing ourselves that the fediverse is actually very simple is going to convince people outside the bubble that that’s true.
Yoshi’s Woolly World probably still counts. It got a 3DS port, but it’s a game whose visual identity is a huge part of the appeal, most of which is lost when running at 240p. In terms of games that probably should be on Switch, I think the Zelda remakes and Yoshi are the last ones. Kirby and the Rainbow Curse and Nintendo Land would both be hurt by porting to a system with “normal” controls, to the extent that they probably won’t bother.
