I hadn't used flash on linux, my primary environment at work and home, for years at that point. Flash was already hated and widely criticized in developer circles. It was already on the way out. Apple jumped on the trend early, but they didn't start it.
I didn't think the developers' community had the power to get rid of flash at the time. Too many people wanted it. When Apple made that announcement I wasn't even sure it would work out for them.
