There was an event I participated about this, I was teaching about gamedev using opensource tools, a lot of people paid to go, the government then brought in a ton of people from the favelas as part of their "digital inclusion" program, although I was happy to teach them, later I heard many of them just stole people's computers, mouses, keyboards, etc... and bolted, a good chunk of the "digital inclusion" people that went for free, didn't sit in a single workshop, instead they just disappeared, and a ton of equipment with them.
Even outside favelas, our infrastructure is just shit too, I work from home and losing power and internet is a constant threat, sometimes water goes out too.
And corruption in general just runs deep, I know a TV producer that was hired to make an Ad for the government, he had to record a government building inside a favela, to make the ad for the government, yet the local government guy wouldn't let him inside to make the recording the government was demanding, he had to approach a congressman about it, and the guy just flat demanded 10k to "do his thing" and make it work.
He did paid the guy, then after that the drug lord demanded another 10k to allow the TV crew inside the favela without being shot.
After he recorded it, the congressman was seen with a new car... meanwhile the drug lord seemly dunked the entire 10k into meat, charcoal and booze and threw a huge barbecue party to the locals.
