I'm surprised that this has reached a head. I had a hard recoil from being involved in financially supporting the tf2 community after the i55 situation. I never publicly told what happened, but it seems like the timing is appropriate.
An invite player would stream tf2 with me as his only viewer. One evening, he was pugging and was in mumble with others. While waiting for a game, Showstopper plays a racist video of Obama. Showstopper then proceeds to comment on the video and repeatedly call Obama a nigger. At some point, Ash chimes in with "I love how racist you are! I fucking hate niggers too!" This went on for a time, but that assertion stuck with me.
At the announcement of i55, I donated ~$600 to Ascent and ~$1,300 to my then favorite team Froyotech. My plan was to foot the entire bill to send Froyo to LAN as a surprise. Before realizing this, Froyotech decided to pick up Ash to plug a hole in their roster. There was no way I was going to pay for a self proclaimed racist to go on vacation on my dime to play video games. After I asked for a refund of my donation, Ash was encouraged to write an apology letter to change my mind. While in the process of writing the letter, he, showstopper, and others were in mumble resentfully referring to me as a nigger.
In 2 years I donated over $20K to streamers and the tf2 community. That all came to a screeching halt and so did my enjoyment of spectating competitive tf2 as an esport. The fallout strained and in some cases ended the relationships I had with members of the community. Here's to hoping the community removes the cancerous elements for the sake of its own health.
