The majority of miners are not a lot more than hobbyists. I am, too. They prefer GPU mining because they know GPUs better than ASICs and because GPUs are more flexible than ASICs. The barrier of entrance to mining is lower.

Additionally, imagine you bought GPUs. Then of course you are going to oppose to changes destroying the profitability of your GPUs. If you then read about someone writing about ASICs fostering centralisation, you'll be inclined to approve such statements.

However ironically it has been shown that quite possibly GPU mining is more prone to centralisation attacks than ASIC mining.
