Because he's been spamming my mailbox every single time he posts with a "LOOK AT MY POST!" message. I have never encountered anyone who does that in my 15 years of posting in online communities.
I should have made it clear in my post when I said "see my PM" that I wasn't initiating, I was just replying to his spam.
That said, I'm honestly not interested in listening to "losing sales to competitors is a GREAT strategy, especially when it's sales that were coming from users with high usage of our client and high monetization."
You guys can say I'm being mean to him all you want, I'm just laying it out. It's a silly argument, and his posting of silly Gaben pictures or spamming my mailbox with messages isn't changing a thing. When you're selling "one-and-done" products like games, being the last one to the market is a bad strategy. That's not insulting Valve. Valve's a great company, and I think 99% of the reason I'm getting so much flack on such an obvious point is that people think I'm besmirching the image of the "Almighty Valve". They can, and almost certain will, improve on this - I'm just pointing it out.
