I have a Synology NAS so I use Hyper Backup and upload my backups in the Synology C2 Cloud. Of course all my files are encrypted first before they get uploaded.
My thoughts exactly. Next is: "OMG did you know there's the all seeing eye on the dollar notes! That means you're being spied on wherever there is cash!!!!"
Stuff like this just makes me wanna roll my eyes.
Depends on what is secure enough to you. For me that is secure enough but I know a ton of people out there who would say it's not secure enough for them. So in the end it's up to you. Think about the risks and make a decision.
True. I recommend a DNS based adblocker like Pi-hole and an extra adblocker like uBO in your browser. If you can't access a website you'll immediately know who is the culprit blocking the site you're trying to access.
Sadly Plex collects some data about its users. I remember opting out of some telemetry stuff but I can't remember where that was. If you want a self-hosted streaming service like Plex that completely respects your privacy, Jellyfin is what you're looking for. I tried it and it's okay but not as good as Plex imo. But if your main focus is privacy then you should definitely check it out. It's FOSS.
Edit:
I found where I had to opt out some data collection for Plex. Open this site, scroll halfway down the page. You'lle see two checkboxes for "Send playback data to Plex" and "Advertising Consent".
Dunno. That would mean websites would know what filter lists inside an adblocker browser addon you use, which I can't imagine tbh. But I'd say it's a gamble. With more block lists you can achieve more privacy but maybe (if privacybro is right) fingerprinting you is easier. You decide what is the right choice to make here.
