Apparently Blizzard, for whatever reason, believes that players enjoy watching other people play Overwatch then actually playing their game. There has been a big push for OWL/Streamer promotions for the second half of the games lifespan so the balance changes generally reflect what is more interesting in the views of OWL and Streamers.
How many events celebrated and promoted the community of Overwatch? Video, music, art, story contests? Promotions and acknowledgement of workshop creators? Many other games have done and have the ability to do these things yet Blizzard has not.
Overwatch players do not matter. Twitch and youtube viewers do.
