If you really want mainstream adoption of self hosting then you need to stop calling it self hosting and rebrand to "personal cloud". The ease of use of cloud software includes zero install, zero management and consumption based pricing. Desktop and mobile had hardware packaged with software and a simple install mechanism with ease of use as a staple for mainstream users.
Self hosting has zero standardisation around hardware, software, install mechanisms. It's a Dev led movement that has everything to do with control and ownership over ease of use. You want mainstream adoption of self hosting. Rebrand it, standardise it, make it easy for non devs.
That's because its a product by western digital. No one wants that. Let's put it like this. Cloud 1.0 was infrastructure, Cloud 2.0 was services, Cloud 3.0 is personal/private.
I respect Western Digital and think they're trying their best to do a good thing. It's that word in general though. Buzzword paradigms always make me feel unwell. As someone who's usually a ahead of the herd in terms of adopting tech, once the broader public catches on and starts making up jargon, I always get a sense that it twists the meaning I personally associated with these concepts and causes me to feel negative emotion about parts of my work life once tacitly normal.
Everything starts out as a buzzword but it's only because it's trying to distil down an entire category into a word. As much as you may dislike it, every industry is quite literally built and defined that way. Something has to be a hook, even if you can explain in detail what it is. Cloud is just this idea that everything goes to a remote place that appears as one thing, which you don't control or manage. In all these trend setting new categories you either play the game or lose out and get left behind as a relic aka like WD, IBM, Seagate and everyone else.
I come from an era of datacenters, colos and whatever else but I learned to adopt new terminology. Cloud isn't just a datacenter, it's all the services on top of it that exist remotely. All the things you don't manage. All the services you make use of. Anything you are not personally installing is in the cloud. That's how we've come to know it and that is the language the mainstream user knows. Just as we'll have difficulty accepting the rebranding of the internet to the Metaverse, it will be a thing that spans far beyond network connectivity.
Who's we? In many countries Metaverse is the Internet by your definition. Lots of PR money has been spent making that the social truth for probably billions of humans. I'm sure everyone over in those continents who likes to use the actual technology that underpins the buzzwords is being force teamed too into thinking they're a dinosaur for not accepting Facebook's dominion.
