I guess to me, being open source is more about the ability that it can be audited. I don't care whatsoever about hosting my own proton mail / drive / vpn (which I use constantly all the time) but I do care if it's audited and secure.
That said, I know they claim to be open source and audited, but I've never double checked those claims. Probably should.
You can already have a wonderful time in Morrowind with the openmw engine. Depending on how far you want to go with mods, you can even make it look gorgeous. It's amazing how much content is there too, with Tamriel, etc... Great time!
The ads are out of control, so no, it's not great unless you use an adblocker, which on mobile doesn't work with the native client.
I use NewsBlur as a backend and Unread as a front end and absolutely love it. For whatever reason unread can often pull the entire article when NewsBlur won’t. Works great!
if you have a seedbox, the easy way to get a good ratio is just to follow whatever release group is popular on the site, and just literally start seeding every single thing they release. Often times on PHD you'll get a free or half download if it's an internal group, and if it's a popular movie or show it'll get loads of downloads. I did this exact thing, and after a little while I had basically infinite ratio and have been using the site for years without even worrying about ratio.
