I don't really think that is true. A pot bonus is not only scoped entirely to the tournament scene, but even further to a handful of guys that have shown they always end up at the top. A shot at a chunk of change is big news to those guys, but there aren't many of them comparatively speaking - even when talking about general entrants. Out of the 700 at EVO, how many people would any of us really expect at having a genuine shot at breaking into the pot money? 10? 15? 20?
A patch may not be something everyone can see benefit from, but it definitely impacts a much larger group of people. It directly affects everyone at every tournament. They all care about it, and it even matters to the enthusiast crowd. People like me who can't really MK good enough to compete, but still are quite invested in the game. I understood what it meant to have Cassie lose her armor on ex flip. I also understood that I didn't care because brawler was getting armor on her command grabs. I've applied that knowledge at home in random fights. I understand patches, and I'm not competitive. I don't know how big my group is, but it + the competitive scene has got to be a bigger number than the competitive scene alone.
You could say feeding the scene with money so there is a show to watch counts for something, but it's starting to get existential, and I think a lot of people want something more tangible than that. If you want the entire public hype over something (Twitter and all that) it needs to be for the entire public. At this point tournament money is a fine thing, but it doesn't feel like news and it's not tangible to the masses, so I think feeling that another prize pot announcement is something different than "big news" is valid.
