Instead of pushing the notion that there shouldn't be money in parkour, which simply isn't feasible, ask yourself, "where are the best areas to put my money that will keep the future of parkour in the hands of people that actually care about it?" We have the opportunity to create a culture that sustains itself internally, but if every time we see a new clothing line that supports athletes or a pay-to-view video come out and we scoff at the idea instead of showing our support, we are indirectly telling those athletes they should provide their expertise to external companies that don't always hold parkour's best intentions at heart. Whether that's a competition sponsored by an energy drink company or a commercial for a company that contributes to deforestation, etc. External companies aren't always bad, but they certainly don't understand parkour or care about its future. Athletes are going to find ways to make money from their passion. The question is, do you want that take the form of long, well thought out videos/documentaries, grassroots events, apparel, gyms, parks, etc.? Or would you rather see the future of parkour in the hands of companies that don't understand what we do and want to exploit it?
This topic deserves an entirely different post, but essentially, the more we support parkour internally, the less we are dependent on external companies. Imagine that instead of the biggest competitions, events and tours being sponsored by energy drinks, gambling, credit cards and alcohol, these events were sponsored by parkour companies: Storror, MYRM, Apex Movement, Storm. Imagine if these companies could sponsor you as an athlete and pay for you to just make videos, blog posts, etc. These things are possible if we foster a culture that supports parkour internally. The next time you find yourself complaining about a shitty sponsor or an event that misrepresents parkour, instead of bitching about it, open a new tab, take out your wallet and buy a shirt from a parkour company that you like. Purchase a pay-to-view parkour video. Invest in a parkour gym owned by someone who has done parkour for over a decade. The more support we give to parkour companies that care about the future of parkour (grass roots gyms, parkour media companies, parkour apparel, paid parkour events/jams, etc.) the less we will have to rely on companies that don't care.
