The article is mostly clickbait. It sensationalize a reality we are already used to: fake advertisement. I'm from Brazil by the way.
I just want to talk about a specific point in the article. When they refer to the digital literacy as lacking compared to the wide adoption of technology. Android is the most common system here, more so if you don't have any money. The one that people find surprisingly complex or difficult. Which means nothing because it's social engineering using people with smartphone cameras.
