Sponsors aren't going to pay teams big money when the only marketing they get back is from good tournament placements.
A lot of the overreliance that the esports industry as a whole has on venture capitalists, sponsors and other external investors could be easily solved if the PPV model had been used by these major companies earlier (or at all), when the industry was still in it's infancy. What esports needs above everything is tangible income streams that can be built and expanded upon, rather than securing just enough funding to operate with vastly overpriced salaries.
Even major esports orgs have to get bought out or sponsored by incredibly sketchy or unethical companies (G2 sponsored by csgoroll, Heroic bought out by russian betting company, ESL owned by Saudi) just to keep themselves from going bankrupt.
As a player that has a regular job to fall back on, it's probably great to make an insane ammount of money for a few years and then just go back to a normal life, but it's a very volatile industry that gets too glorified.
