Bundled games

I seen many games in bundled. And it counted as bundled. Even if i buy it in steam store. Why? It completely unfair.
For example "Eidos Anthology". It not cheap, buy it in steam store, i thought it really good. But today i seen it in bundle games and... it bundled O.o Why? It even not been on bundles and don't have low price.
I feel left out, cause i receive only 15% for eidos anthology, for example.
So, with this logic soon all games will be bundled?
What you think about this injustice?

I think SG need other system. Where games from steam market can't be bundled. Only very cheap. Or something else.

Update: Mostly think about justice here. But in our region, for example, average salary 250$ in month. If you have received these money, in this case how would you have voted?
