I wish it was open source. I used to use Obsidian until I started to replace everything with FOSS alternatives. And from all the proprietary software I used to use, Obsidian is the only one which I miss.
I’ve tried logseq, Joplin, rnote, zettler, silverbullet.md, and a long list of alternatives, but nothing comes close to Obsidian…
then the idea becomes ever less viable because only a handful of devices will be able to be used.
for the price of a Pixel you can buy a competent desktop PC that supports a real OS with networking tools, without an EoL cycle imposed by the manufacturer, with upstream kernel support, with replaceable and upgradable components and a long etc.
a security nightmare, phones are updated from 2 to 4 years and then left for dead. after that no more security updates and apps will eventually stop supporting your version.
also, android lacks proper networking tools. no root access is also a big problem when selfhosting.
oh and let’s not forget the unlockable bootloaders that will lock your “server” into an Android version full of spyware and whatever crap the manufacturer decided to include.
but even on a a clean Android like Lineage OS, Android is unsuitable for an OS because it’s ultimately designed as a phone OS which are too restricted for self-hosting or doing serious computing at all.
they also have zero reparability and upgradability. if my storage runs short, I just buy a larger HDD and replace the old one. Cloning the disk is as easy as using one command, good luck cloning your whole system in Android. If my CPU dies or I need more processing power, I buy a new one and plug it in.
at this point you’re probably trolling but whatever, here’s a Duckduckgo link since you “can’t afford” googling
if the hardware is compromised, then most phones are since they are all manufactured in China, even Apple’s.
