Most “privacy guides” like that literally just shift trust from one party to another.
Banks are starting to have temporary credit card numbers themselves for a purchase. It depends if you want “privacy” or “anonymity” as it seems like the person in the video wants the second.
Nowadays there are precious few actually private or anonymous email providers themselves. Maybe Posteo or Tuta? But I don’t know their audit history with leaking metadata or handing over logs and information when asked.
Honestly I have accepted that if I have to buy online, there is always a paper trail. Buy in-store in cash when possible, use second hand websites in your area. It is better for the environment too. Anything digital will have a paper trail that can always be de-anonymized with enough effort.
All my electronics hobby stuff I have to buy online and I just do this with my normal credit card, especially since they have export controls in many distributors and if you get caught using fake credentials they will likely blanket blacklist you as someone trying to bypass export controls and use medical/consumer sensors and devices for weapons, against the companies’ restrictions.








For some things.
For many things it isn’t. It is usable (I use it) but with a bunch of workarounds for anything embedded development-related since it needs specific vendor software with device access. I have had to use a variety of distrobox + app image solutions that are often a bit worse than a system that installs them as native apps.
