Quem tem medo de Spectre & Meltdown? / Who’s afraid of Spectre & Meltdown?

By Alexandre Oliva, GNU, FSF Latin America, LibrePlanet São Paulo

These architectural bugs, that became publicly known in early 2018, have caused major panic and still worry a number of people, from home users to microprocessor designers. Some of the fixes or mitigations involve installing proprietary microcode. When collected data about users is worth more than oil, where Intel ME and similar technologies are denounced as backdoors and computational security swiss cheese, and USian businesses are discouraged from using Russian antivirus software and cell phones of Chinese design, whom can we trust? What lessons can the Free Software and similar communities learn from this? Does that who did not fall for the tales of the World Wide Web (WWW) of Execution or of Foggy Computing, nor is making victims with them, have anything whatsoever to fear (but fear itself)?
