I disagree quite a bit with the idea that it's all the same because it changed. Juninas have always been dynamic, yes, but what's happening now is different in speed and in priorities. Before, changes came organically - people brought new recipes, new rhythms, but the focus stayed on the community gathering together. Now there's a business model behind it, with influencers and production that turns the spectacle into content before it's even a lived experience.
The question isn't whether it changes or not - it's that the essence is being replaced by something else. When the traditional stalls get sidelined, you're losing what was the main point: that stall of dona Maria with homemade broas, people chatting, the girls learning recipes from their grandmother. These things are really hard to go viral with, so they become invisible at a party designed for phone cameras. The giant LED stage is spectacular, but it's outsiders watching something that isn't theirs, while the people who used to actively participate end up reduced to extras.
That said, it doesn't mean the party stopped existing - just that it needs to coexist with this new version. Many cities still manage to keep both things running side by side, if there are people interested in preserving it. The real question is: who's organizing this and for whom? If it's for the local community to enjoy and generate income, fine. If it's just for social media content, then yeah, the essence has left the building.
