It's not about you being in bluetooth range of the person you want to talk to, it's about all the people sitting in between you both that pass the message along without touching the internet.
So you can be on a cargo ship, or on a remote island, with 20 other people and all use chat. If 1 person has internet, then you can all chat globally as well.
It's the same basic method of how airtags work. Everyone with an iPhone connects to the airtag and passes data to Apple. It's just done in the background, so users don't ever notice.
You have to do something physical. Run, do some intense workout with cardio and weights, wail on a punching bag. Maybe all 3.
Let your brain focus on something that isn't words in your head, and exhaust you physically, and you'll quickly learn how inconsequential other people's petty BS really is in the grand scheme of things.
In a few cities it's good. NYC, Chicago, where white people live in DC, and maaaybe SFO come to mind. (LA your subway is only for movies, F off). Literally everywhere else it's a travesty of busses designed to institutionalize and reinforce classism and poverty. So it's bad, and no one wants to use a bus system (lack of tracks? Lack of charm!) of it served wealthier neighborhoods.
I used to at work. I would do a half filled mug, give it 2-3 minutes of heat so it didn't suddenly boil over, then drop in the tea bag and fill with regular water.
It's worth it to pay extra for anything that doesn't need an app or WiFi connectivity.
Those are huge red flags. Avoid anything "smart" like the plauge.
Appliances with "smart features" are simply scraping your whole home, not just your phone, for data to sell to advertisers. Very often the app or even the company won't outlive the appliance itself, so as happens frequently, in 2 years you'll be stuck with a perfectly workable appliance that refuses to work because some server in China went offline.
Aside from the Ars Technica article in the xpost, there's a lot of "it depends."
It depends on not just the OS, but if it's a custom image built for Dell or HP or Asus etc. computers, what settings are on, what settings were on by default, what bloatware is pre-installed, etc.
Typically, all MS or Apple really want are to know what apps you have installed, zip code, email address, IP address, crash reports, and possibly keywords they can associate with advertising. That's their baseline wish list, which is all advertising fodder, and depending on your settings, that can quickly expand to "anonymized" (it's not) cookie use, tracking of websites visited, etc.
If you have a custom image (i.e. a Dell specific version of Windows) the laptop manufacturer will look for access to roughly the same data.
With the whole Copilot fiasco, recording things like keystrokes and screenshots really are potentially in play now. But, again, only if you have foolishly installed Copilot and turned that stuff on. And that only after huge public outcry. So there's always a non-zero risk of that, but do your due diligence to know you settings.
Can you strip out bloatware and tighten down Windows to a reasonable degree? Sure. But because MS can and does change system settings without your consent, you might find in 6 months an article about a setting you turned off, that they turned back on and you had no idea.
"Just" as in nothing that demands a phone number to validate. Meaning that OP will be asked to enter a phone number when signing up and may not have to worry about it being the same one as their email account.
In /r/privacy they started implementing the new social credit system where not only do you need karma, you need fresh karma, called a "Contributor Quantity Score." So my usual aged, pop in every few months account with decent karma is effectively banned for being (actual term) "lowest value" because I'm not on Reddit commenting every day.
Agreed, I was warned off of PIA 5+ years ago.
