Why does Riot lie to its paying customers?

I am curious how a company can constantly lie to its player base and think in the long run this will help their game.

Another question, does Riot think that lying to players who mained Mord and Veigar for YEARS and nerfing the 2 already weaker champions helps grow their game or make players quit?

**Riot isn't even trying to enforce a meta anymore. They are wiping out 15%~ of the champion roster with each new hyper CC/mobile champion release and giving already OP mobile money making champs like Zed Lee Nid and Ahri either a free pass from nerfs or even "reworking" these champs in a way that still makes them incredibly powerful. **

The writing is on the wall for the direction of this game and I cannot believe I am watching Riot alienate its old playerbase.
