I love the idea but not the messaging. Older folks & non-nerd people - a vast majority of the demographic of people who would benefit from this campaign, if I had to guess - aren’t going to want Linux or “fresh new software”. They want a computer with a web browser, an Office suite, and an OS/layout that functions exactly the way they expect it to.
If you tout so much change, they’re going to lose interest. I’d argue they’d lose interest seeing technical words like “software”, since all they know on phones and computers are “apps”.
However, If you instead show them side-by-side how they can do the exact same tasks with nearly identical steps and also emphasize the benefits like cost effectiveness and speed… they’ll just say “okay great, can you do it for me?”
If that’s really a concern, USB or PCIe NICs are always an option as a replacement, whether temporary or permanent. More advanced users can create virtual connections to route traffic through (macvlans) with custom configurable MAC addresses and/or use virtual machines that offer the same feature if a guest OS is preferred or necessary.
The identifier the article is talking about is instead persistent on any Windows OS regardless of hardware, including if the OS is a virtual machine. Using the OS at all on the Internet ensures Microsoft can always track it.
