Curation rewards are insubstantial now, and even doubling them as this proposes will remain insubstantial. People come here to participate in a social network that rewards them for contributing - which is why people join social networks.
The bidbot owners want to extract more rewards faster, and EIP makes that happen. It will be the last gasp of Steem, as the last bits of value are extracted before the profiteers move on to the next victim.
Users are the source of value for Steem. Anyone that says we can just get new ones just isn't interested in making Steem more valuable. Each user cost funds to get, and when they leave those funds are simply lost. Replacing them then costs new expenditures. The people you're getting this from are profiteers, and in order to grab the last scraps of value possible they need to get liquid Steem sold quickly before the price reflects reality. This will accelerate the rate of extraction and increase the USD price of the Steem they sell.
Bidbot owners are poison. Don't listen to them. They don't have the communities interests at heart. Just their wallets.
