For those who can't watch the video:

1. There is no way that Riot knows that LCS teams are funneling the money they earn through League sponsorships into other esports. He went and asked every team if Riot ever asked for revenue sheets. None of the teams said so.
2. There is indeed money in esports. Monte used an example with REN made 10X as much money from CSGO stickers than from summoner icons. Businesses don't go into esports believing that they will get nothing out of it.
3. Therefore, Riot almost certainly makes money from League tournaments. When the client pops up a window touting the latest LCS match, the people who watch the games will not be distracted from external advertisements and etc., only showing the latest skins that the pros are playing. Monte claims that Riot almost certainly has marketing data showing that the LCS dramatically increases the likelihood that players buy a skin after seeing a match. In his own words "it is highly profitable for them." While casting Worlds, Monte would have to create champion packs that would be sold in discounted bundles. There is no profit sharing. Riot gets everything.
4. Tencent would have stopped the esports realm if it lost them millions of dollars for no reasons. It was always an option that Riot could sell the broadcasting rights to a third party for a lot of money from sponsors because "the game is huge."
5. It's Riot's imperative, not the teams, to increase player salaries via sponsorships and etc. Why not the teams? Because teams are already paying their players a reasonable amount of money. Nobody is paid the Riot Minimum, not that Monte knows of. If teams don't spend money, they are threatened by relegation constantly. Relegation ensures high competition for good players. If Riot is concerned about pay, they should raise the stipend, as it hasn't been since 2013. The game is much bigger now than it is then. Riot made 1.6 dollars last year.
6. Riot is the "fucked up tyrant Santa Claus" who determines who goes on the naughty or nice list. Regi is part of the nice list arbitrarily.
7. Salaries for players doubled or tripled since the entrance of venture capitalists. Regi is certainly paying his players top dollar. Monte claims that teams are actually willing to pay their players at a loss to build a brand, placing more market power into the hands of players over their owners. The logic behind this is that teams are willing to lose a little bit of money now to make an incomparable amout later on. Monte "broke his budget" paying for his players on REN.
8. (He goes on a sidebar) Casters. Riot was offering rates that were roughly 40 to 70 percent of the "industry rate," that which is seen in Halo, Dota 2, etc. Monte asked Riot to pay him the industry standard rate. Riot said no. That's fine. It's their prerogative. CSGO casters make twice as much as Riot casters. Monte posits that all casters should be freelance casters, basically having all of the rights that Monte has now (streaming, casting for leagues not associated with Riot, getting sponsorships, etc.) Monte made more money than any Riot caster casting alone. Riot casters have a flat salary, regardless of how much work they do. MSI and worlds is extra work. In fact, at IEM tournament, casters are basically loaned out for free by Riot. Everyone else is paid directly by ESL. Jatt, Kobe, and Deficio can't make VODs or build their own brands because of Riot. Casting is inherently a talent job, not a salary job that pays relatively little. Dota 2 casters made as much in 3 weeks at TI as Riot casters in six months.
9. Teams are very player-oriented. Teams are not making millions of dollars of the LCS because player salaries are at the highest they've been.
10. The patch fundamentally changed the game. Every player that he has spoken to has hated the patch.
11. Laneswapping is a skill. Some teams actually signed players that were good at laneswaps. Rosters are locked. They are screwed.
12. We don't know that Doublelift and Biofrost can actually compete against the best in the world. Riot doesn't know jackshit about what skill is. Riot wants League of Legends to look like solo queue, which bolsters it as a marketing tool. They don't want viewers to be confused. They want to cram League into the most efficient marketing tool to sell skins.
13. The fact that teams are forced to cater to sponsorships takes away from practice and leisure time, making player lives worse. Riot could step up and take more of the burden by sponsoring a mouse, a headset, or a computer, but they refuse to.
14. Monte makes the majority of his money from other esports projects. He has perspective on other esports and claims that Riot is very much out of touch with its own scene and other esports scenes.

Edit: 1.6 billion dollars. Sad days.
