What open source can do for:
Free and open source software (FOSS) is a wild dragon-child that can transform any organisation into a Daenerys Targaryen. But like her, you need to know how to tame this dragon, and where and when to use this effectively. Otherwise, its fire can and will consume you instead.
An individual (home user)
Whatever software a home user adopts (including proprietary and commercial software), open source offers fierce competition to push costs down, keep it free, enhance its performance, make it secure, or honour your privacy better. Hence, open source browsers are free. Home users get operating systems for free or a token fee. The latest Firefox outclasses even Google Chrome, while Telegram messenger and Signal outshine WhatsApp with their privacy and security.
Techie home user
That’s like singing to the choir. For the techie home user, open source is the best way to tinker and hack and, hopefully, also build the next billion-dollar unicorn in your barsaati.
