Steem-agora spread half truths and distorted facts about upvu and upex in order to poach users for his avle voting service. It worked to a degree as many users blindly trusted him. If users deem that voting services are charging too high of fees they are free to use a different service, or no service at all. Apart from all that, his main point about voting services decreasing the price of steem is very likely not true and possibly the opposite is true. By users being able to earn a high rate of return for their steem, it encourages investment. The more you buy, the more you can earn etc. If we want the price of steem to increase we need to build things that buy/burn steem in exchange for a service. Things like that are ideal use cases. I also mentioned using the SBDs in the DAO to buy and burn steem with the intended goal of transferring the excess value in SBDs back into the market price of STEEM thus helping restore SBDs to their $1 intended peg.
