Your question is beyond software and is related only to business.
Freemium model gives companies marketing, additional traffic, potential customers, test results, feedback. Some tools are used to support other products or business overall. Chrome and other browsers is an example. More people use Chrome, more control Google has on the Internet market. Google search and advertising is main Alphabet's source of revenue and to be the Leader on the market, Alphabet has to adapt all the time, thus, you see Open Source OS for mobile - Android, Free and fast browser - Chrome, open source ML library - TensorFlow, and much more. When you look on a bigger picture, you see that all those "free" tools for you are not really free. You see Google ads, you give your privacy and data to them.
Free software not only provides in most cases bad quality, instability, awful support, but takes market share from commercial software and engineers' money. It means that price is higher then it could be without free alternatives.
On the other hand, more competition is always good. Overall, it forces some tools to become better, offer much higher quality services/products, new functions, simpler UX, whatever.
Free software, after all, allows anyone to achieve more goals, be more independent, and move technology and humanity forward.
