To be fair my Windows experience was far simpler than Linux, if less fulfilling. What got me was a combination of constant attacks on privacy, W11 and the enshittification of the UI as well as general Microsoft corporate tomfoolery (have dealt with them for work, not a fan of their monopolistic EEE tactics).
Honestly I only ever learnt Linux admin by troubleshooting my borked Arch updates, necessity being the mother of invention and all.
