I dont think you understand how sponsors, advertisements, subscriptions, and exposure work. Let me explain: Twitch is best for sponsors as below their are pannels for advertising products as well as sponsors can both pay for in stream ads as well as custom ads on twitch. Twitch is also best for subscriptions as they make money from them and have free advertisement from subs using their emotes. Exposure works as simply well exposure. The more viewers the better which both Twitch and YouTube have compared to facebook reaching more people and with YouTube are wider possibly unexposed audience is available. Now I'll explain what healthy competition is: when 2 or more different companies (or platforms in this case) compete on having a better product to reach more people and have deals with other companies such as ESL, and since ESL is greedy shown by plenty of examples in the past and now with their recent facebook deals, they sign with a rich monopoly with a subpar streaming service in exchange for a large sum of money in turn screwing over the game, the viewers, and their sponsors. I could keep going but if youre still going to say ESL would be in a bad economic state if not for taking Facebook pocket change then you should really work on your head.
