Sorry you feel this way.

There is no monopoly here, post just appear on steemit as well as on photostreem when you use the photography tag. You are free, just as anyone else, to create your own tribe for the photography tag as well. We will put in the effort to keep our tribe clean and the level of content high. That is why we include the good projects. Not to get them on our side, but because we are on theirs.
