I cancelled my O'Reilly subscription because it's cheaper for me to buy the books from the publisher. I go through one book every few months. I thought I'd go through more with unlimited access but I didn't. $539.88 a year vs maybe $140-$200 I spend on books (I take advantage of discount codes when they come up).
I also like to go back to books. I cannot do that with the O'Reilly platform when a subscription ends.
I hear you and agree on the unlicensed training point - it is a form piracy.
I'm similar, I think perhaps it's a generational thing which slightly modified the title in a pedantic way.
The people who "grew up" with text books still crack new ones and old ones.
The current generation turning 18-21 don't.
It surprises me because I'm often asked why I knew X or Y odd perhaps esoteric fact or design pattern. Usually it's because I came across it in a book interested in something else.
It's that peripheral knowledge that is being lost when people use LLMs, and quick start guides.
Historically you'd have a team where skill, knowledge and experience was very variable but each person often brought another piece of the puzzle to a team.
Increasingly people have narrow knowledge "bases".
Does it matter? Perhaps not but it definitely has taken some of the joy of discussing problems and solutions out of my working life.
