That’s no different from VMware or Hyper-V if you switch the specifics around. There are many more administrators running virtualization clusters that have very little knowledge of the internals than there are subject matter experts or weekend deep divers. The barrier to entry for these things is low because they’re designed well enough and half decently documented. Proxmox isn’t unique in this respect.

OK. So we have a disagreement then. What part of Proxmox requires expertise?

I’m not sure I’m parsing your fifth paragraph correctly. Are you suggesting Proxmox is DIY and unsuitable for Production? That Proxmox is suitable for Production and those who think they can roll their own hypervisor are in for a bad time? Something else?

That’s not true for all sites. If the page is static then it’ll have no clue. If it’s dynamic and running a client-side script to report this info back, and if that information is collected, then I can see how that might be a useful supplement for fingerprinting if the server owner is so inclined. At that point though I’m wondering why a security-conscious user is raw dogging the internet and allowing scripts to run in their browser without consent (NoScript saves browsers).

Even then it’s unclear when/how altering the page to render it differently is commonly communicated back to the server, how much identifying information that talk-back is capable of conveying, and how we might mitigate those collections (wholesale abstinence and/or script control aside). What are the specific mechanisms of action we’re concerned about? This isn’t a faux challenge for the sake of hollow rhetoric. I’m ignorant, find the dialogue interesting, and am asking for help being less dumb. :)

I found some brief and useful discussion in this Privacy Guides thread. Seems like the concern is valid but minimal for all but the most strict/defensive postures.

Trying to validate this myself for Dark Reader without breaking out Wireshark and monitoring some big tech site while I toggle color modes (which I might do later if I think of it and find the time) I see Dark Reader is open source, an Open Collective member, and seems to engender little hand-wringing. The only public gripe I can find is this misguided Orion Browser feedback thread.

Thanks for the interesting diversion!

How so?

This is admittedly a bit pedantic but it’s not that the risk doesn’t exist (there may be quite a lot to gain from having your info). It’s because the risk is quite low and the benefit is worth the favorable gamble. Not dissimilar to discussing deeply personal health details with medical professionals. Help begins with trust.

There’s an implicit trust (and often an explicit and enforceable legal agreement in professional contexts (trust, but verify)) between sys admins and troubleshooters. Good admins want quiet happy systems and good devs want to squash bugs. If the dev also dons a black hat occasionally they’d be idiotic to shit where they eat. Not many idiots are part of teams that build things lots of people use.

I’m excited to see they’re going fully open source. Looks like the last steps to making the sync server self-hostable are in the works. Do you use their paid service? If so: any complaints or caveats?
