You're not wrong, there is an aversion to change.
The reality too is that using "the one they're familiar with" is what gets work done.
Nobody wants to climb another fucking learning curve unless it ACTUALLY benefits them (and even then, there's a cost-benefit calculation to the time-to-payoff).
Microsoft - and more and more SAAS bullshit companies - keeps just *changing* shit for no reason (cf the 'start button in the middle of the bar' in Win11). MAYBE they add some teensy feature but imo 95%+ users could be using Word 2.0 and it would perfectly serve their daily needs.
So what users are seeing now is a constant fluffery of 'change for change's sake*". Is it surprising they are resistant?
*we all know it's just so MS can sell some more and CIOs KEEP ACCEPTING IT. Why? Honestly, if Corel just built a bulletproof basic-featured 1990 version of Wordperfect and sold it AS IS in totality today, no 'web awareness' no 'AI collab feature' no constant tweaky updates...hell, it might rise from the dead as a real competitor.
