Over the last 30 years the culture and power has made a gradual shift from 100% pure hobbyists to 4% hobbyists, 48% scammers/predators, and 48% commercial.
You can't pinpoint when the fun stopped and it's subjective. I personally became conscious that the party was fully over around 2023, after a few years of feeling it subconsciously.
2023 was when Twitter and Reddit changed their respective APIs and became openly user hostile, which was the symbolic turning point for me.
