I'm thinking about an online conversation I am having.... I'm scratching my head, because I know why I started using Linux. Privacy and Security were my main two reasons. And thought that was the main reasons why most people start using Linux.
There's quite a few responses that reflect upon this question around starting linux in this thread from December 2024 where the OP asks "How did you start using the Linux operating system?" here:
https://www.linux.org/threads/linux-operating-system.54628.
In post #10 my own immediate reasons were outlined for moving to linux. It was security related because the windows operating system that I was using caught an email worm that infected the machine. That experience was extremely disruptive and annoying at the time so windows was discarded and replaced by RedHat linux.
In addition to that practical reason, the open source nature in the philosophical underpinnings of the linux ecosystem were also very appealing.
One influential reading was by Eric S Raymond called "The Cathedral and the Bazaar" about which there's info here:
https://en.wikipedia.org/wiki/The_Cathedral_and_the_Bazaar. Basically it outlined two models of software development, the more authoritarian one dubbed the "Cathedral" in which development was controlled and progressed through a controlling group with all the constrictions that entails, and a second model dubbed the "Bazaar" which is the open source model enabling contributions from anyone from anywhere to be made for the development of the project without the Cathedral type of constrictions. Linux was founded on the Bazaar model in this conceptualisation.
The Bazaar model closely resembles the open nature in the common practice of science where the developments and results of the seeking of knowledge are freely shared for the ultimate advancement of humanity. On-going research and results are usually published in journals or by other means to be made freely available for the benefit of all and especially for those who are interested.
Another aspect that made linux appealing was the story of its origins from a student who followed his own curious interests, made some initial headway and invited anyone else who was interested to develop his vision together with him. There were no company commercial imperatives, no organisational pressures, rather just an individual working much like an artist might create their work to fulfil a vision they have. It's an inspirational story which is outlined in the book of 2001 called: "Just for Fun: The story of an accidental revolutionary" by Linus Torvalds and David Diamond. It's freely available online from a number of sources as a pdf.
