It is part of the SSSCA / CBDTPA / "Trusted" computing initiative. The large corporations want to control what you are allowed to do with your computer. This is where the phrase "digital rights management" comes from.
There are many Android based OS for phones. Graphene is a privacy focused Open Source OS which already fills the niche Apostrophy supposedly does. https://grapheneos.org/
It looks like it is powered by a microcontroller. Maybe it isn't powerful enough to support epub?
Any good substites on FDroid? Specifically SMS and file manager?
A second USB port or headphone jack adds $1(US) to the manufacturing cost, if even that. Can't cut into the corporation's massive profits by even a little. Nope, can't have that.
This seems to be the reason why I don't use Amazon very much anymore. Almost every time I search for something, most, if not all, of the results have nothing to do with what I wanted. I can't be the only one who has stopped using them because of this.
Anyone have better recommendations for online shopping?
Java isn't an interpreted language any more than C. Java gets compiled into its own machine code developed by Sun. That machine code can be converted to native code or just run "interpreted." (which is more like emulation.)
Maybe you should learn more about something before you criticize it.
This was started over two decades ago, but never came about because the copyright cartel destroyed it. It was called peer to peer (p2p) tech.
The cartel even tried to pass laws which would allow them to control what media you could have on your computer. (The SSSCA and later CBDTPA) This is where the term Digital Rights Management came from.
One possibility is an instance shutting down. Many instance admins are good about giving lots of notice, but sometimes that doesn't happen.
In fact there has been at least one instance on the fediverse which the admin disappeared from the internet, and their instance just slowly degenerated until it stopped working. Were they hit bt a bus? Who knows.
Christian fundamentalists want to keep everyone from viewing porn. Keeping it from kids is just a smokescreen for them. One of the big reasons there aren't sensible things in place to reduce kids seeing such things, is because the Christian fundamentalists will take over that effort and try to force it on everyone.
And in the early days of the telephone, switchboard operators would listen in on conversations and cut off anyone they didn't like. Then in civilized countries, they required phone companies to be common carriers and required police to get warrants if there was anything illegal suspected, to listen in on someone.
Similar thing with the postal service.
