the concern is that it's decreasing in popularity over the years, and if that keeps happening we're going to start having less of it. Not just less cricket to watch, but less opportunities to play and fewer people to talk to about it. Which is quite sad tbh. Imagine growing up spending all your time playing and watching a sport you love, but then as you get older it becomes harder to follow or take part in, all because everyone around you seems to have lost interest, and as a result the sport is forced to go commercial and gets hidden from public view as a result.
We're already losing out on great 5-match Test Series in exchange more commercial and easily sold formats. The IPL already shuts down cricket for 2 months a year. And if you're a fan living outside of traditional markets, your access to the game - be it watching or playing - is so limited, you may as well switch to a different sport.
Cricket's still very healthy, but for all the talk of being the '2nd most popular sport in the world', it's really just popular in the subcontinent, and everywhere else it is well behind sports like football, tennis, basketball, and arguably even rugby. Perhaps it's behind boxing and MMA as well. And maybe more sports I can't remember off the top of my head.
That's why we all want it to be more popular. Just to safeguard it's future, and thus our happiness.
