First, I don't think the problem is actually the number of event, but rather this high number is a symptom of a high demand/high involvment from the fans of the game. To compare it to something like go, there is not many players(in europe), almost no "viewers" since all tournaments in europe are ama, that means that everyone can play in them. But there is still a great number of tournaments, because the game calls for a lot of competitivness and becasue the fans love their game so much they are willing to put time and money into it(be it events or products/support).
So the number of tounaments is in my opinion the result of a highly competitive game in nature and a higly involved fanbase.
Second, I hate when people talk about ads as a painless way to make the viewers pay. Not to enter a fruitless debate about the consumerist society, I believe the overabundance of ads is actually quite painful to the viewer.
Furthermore, I feel like the ads are actually part of the problem, because there are so many of them in e-sports, it makes watching events tedious, boring, and sometimes frustrating, -just by seeing the same stupid ad 20 times between 2 matches, the viewer lose a big chunk of his excitment-.
Finally, I loathe the idea that viewers would have some kind of "duty" towards the events they watch, like disabling adblock, or buying stuff. I feel like it ois the role of the sole company to sell its products, and if they can't make people buy it, then they need to revisite their package, not beg for people to swallow it forcefully.
on the other hand I rather agree with some other points raised in the topic ingeneral:
1.- the point that sc2 is not a casual game and therefore wil never have the casual mass appeal that LoL have(regardless of the skill it takes to play it at pro level).
2.-the point that there is not enough diversity in the formats of the events. I feel like some 2v2, or even 3v3 tournaments should be implemented, as watching a team playing has its own appeal that 1v1 will never have (and conversely)
3.-The point that there needs to be more continuity on the storylines. But that do not mean less events, but a cooperation between companies (what MLG/ESL is doing, or IPL/GOM etc) so that events build each other up. In tennis there are many events, but they all build up to le grand chelem, a set of tournaments with largely differents formats and content, different enough to justify to each a big final event of its own.
And I would also like to add a point of mine, which is that players needs to start realizing that they are in the entertainment industry, and at least try to shake off the awkwardness of their interviews, they stages appearances, and so on, lest the events supress all of that completly. And on the other side, tournaments have to lose their own awkwardness, like endless downtime, shots of empty venues, uninteresting side "content", and so on.
