Brazil`s change to open source

after hearing the podcast. it appears to be about Brazil's changing from Microsoft software, which Brazil has to pay for, which Brazil has already paid 1 billion dollars to the Microsoft industry already and in order do save the country money, Brazil has decided to change to open source, which is in a Linux system. because of this the country of Brazil is going to save billions of dollars in the future by having made this change from Microsoft software. i also learned from the podcast that Microsoft has 90 percent control over the software industry in the world. i think Brazil change to open source is a good idea and more countries should do the same. Microsoft has to much control over the software industry in the world. i like open source myself and hopefully in the future as Linux gets more user friendly it will become the dominant software used in the world. this way companies like Microsoft would have to lower their prices in the products they sell, so that it makes them more affordable to people of lower income if they choose it. unlike right now were we have to pay over a hundred dollars if we want to stay updated every time Microsoft creates a new software system.
