I said this years ago: open source always the brides maid, never the bride. That or its a bit like atlas, holding up the burden of capitalism.

Either way the internet is still just a big ip network. You can still setup a vps and run your own email, website, rss, blog, etc. And I know some people (masochists, psychos?;-) who do but they do that admin work for a living. Yeah, you gotta roll up your sleeves but that's just life: you have to work for it. These companies prey on human laziness and "free" stuff.

Just stop using garbage services and take back control. I'm one of those technological troglodytes who refuses to participate in most modern web nonsense. I have a smart phone with only a few utilitarian programs. I don't use any social media. I use bandcamp to stream/download my music collection which I paid outright for. I don't have any smart appliances, TV's or IoT trash. My life is fine and I have plenty of friends and a social life. Don't let anyone fool you into thinking you need to drink the dumpster juice internet koolaid.
