"I think a free product have to be utterly superior to a paid product in order to displace commercial products." In order to completely displace commercial products, yes. But for any reasonably complex or powerful product, there's a market of customers that are overserved by it and would pay less for less if they could. This is usually handled by product segmentation - think of options in cars. If you don't need the extra power, go for the 4-cylinder instead of the V-6. If cash is more important than comfort, skip the leather seats. If you need the fastest, most luxurious car and money isn't an option, check every box on the list.
