I'm not really sure what the overhead is since I usually have 16GB or 32GB of ram anyway.
That aside I feel the article is applying a double standard. Someone who properly can use Linux can easily resolve most of the authors criticisms. It's also possible to run Windows (haven't tried on 11, but is possible with 10) on a USB stick or external hard drive. You can also install Windows (10) trivially on most machines. Certain Linux variants also have telemetry, etc.
I enjoy Linux, I also enjoy Windows. There's no need to create a false dichotomy. It's very easy to just run both. Best tool for the job and what not.
