buys … from commercial brokers
Y’all are seeing the real problem here, right? Your data is just available for anyone with the cash to pay for it. Stopping just the NSA from buying this data is attacking the issue from the wrong end.
There should be protocols and practices in place to stop our data from being owned and sold. Hence why I take the steps I do to help anonymize myself to a small degree. Ditch Facebook, ditch apple, ditch google, ditch Microsoft, ditch any provider that wants to claim your data that tou can to minimize this sort of behavior.
Serious question: Do you browse this app, or similar sites, on an iPhone or Android device? If so, how are you getting away from those companies?
As MajorHavoc said, there are ways. I do in fact use GrapheneOS, have access to a reasonably secure VPN, I use Firefox as well as Vanadium, within Firefox I use Ublock Origin and a few other tools. Some argue that having as many layers of “protection” is counterintuitive because it makes your fingerprint on the web more unique.
GrapheneOS is a good start.
So is brwsing with Firefox and uBlock origin, and a VPN.
There’s a ‘deGoogle Yourself’ Lemmy that gives lots of guidance (and it works beyond just Google).
