He's unarguably right, I'm just not necessarily sure it's a bad thing. Obviously it's bad that they're not competing in big events, but for the individual person it's likely very good.
While those people who are worried about streaming, social media and branding may not be winning in Siege, they're most certainly building something for themselves that can outlive the game. These guys are probably 20 y/o on average, this shit isn't taking them to retirement championships or not. They are eventually going to be doing something for a living that isn't playing Siege. The people who are focused on personal branding and such now are going to have a much easier transition when that time comes.
