  • There are too many differences for me to list here, but unlike mobile operating systems, Windows and most Linux desktops do not provide sandboxed environments for userspace apps by default. Apps generally have free reign over the whole system; reading/writing data from/to other apps without restriction or notification. There are virtually no safeguards against malicious actors.

    Mobile operating systems significantly restrict system-level storage space, making key areas read-only to prevent data access or manipulation. They also protect app storage, so one app can’t arbitrarily access or modify data stored for a different app.

    Mobile operating systems also follow an image-based update model, wherein updates are atomic. System software updates are generally applied successfully all at once or not at all, helping to ensure your phone is never left in a partial or unusable state after a system update.

    For desktop users, macOS, and atomic Linux distros combined with Flatpak are the closest comparisons.




  • No, the average user will never know the difference. I couldn’t tell you exactly what the current performance impact is for hardware encryption, but it’s likely around 1-4% depending on the platform (I use LUKS under Linux).

    For gamers, it’s likely a 1-5 FPS loss, depending on your hardware, which is negligible in my experience. I play mostly first and third person shooter-style games at 1440p/120hz, targeting 60-90 FPS, and there’s no noticeable impact (Ryzen 5600 / RX 6800XT).



  • While it would certainly be nice to see this addressed, I don’t recall Signal ever claiming their desktop app provided encryption at rest. I would also think that anyone worried about that level of privacy would be using disappearing messages and/or regularly wiping their history.

    That said, this is just one of the many reasons why whole disk encryption should be the default for all mainstream operating systems today, and why per-app permissions and storage are increasingly important too.

    First, it’s important to realize that Meta is likely tracking you already through its ad-related services even if you don’t have an actual FB account. Countless retailers and services are using Meta and Google for ads and analytics and it’s virtually impossible to be completely off their radar if you do any online shopping, banking, or service consumption.

    Even with the use of VPNs, uBlock and other tools, Meta likely already has your particulars, including full name, phone number, email, and physical address simply by way of family members and colleagues saving that information to their own address books which are then shared to Meta through FB, WhatsApp, etc. In this way, your name, phone number and/or email address has likely already been associated to otherwise anonymized data through retailer back-ends.

    That said, if Marketplace is important to you I would simply create a FB account and use it solely for that. I would avoid installing any FB/messenger apps, and opt for a browser-only experience in order to minimize additional privacy infringement. Use FF containers, incognito mode, or a separate browser altogether for FB access if you feel it’s necessary.

    Meta has taken a hardline approach to fake/obfuscated accounts, so I suggest using legitimate tombstone info but only provide what’s necessary for account generation. Anything less and you’ll risk a deactivated account, or Marketplace ban.

    Don’t overthink it. If you use the platform with basic care (no apps, no persistent cookies), then the most they’re going to glean is that you like shopping for retro games and other used goods.
