The author hasn’t been watching the full cycle of all the “free” stuff. With the internet, many start providing beta versions of apps/etc. for free and collect data to enhance the product. Once they are comfortable that they have a truly marketable product, the freebees stop. Others (Malwarebytes, etc) offer toned-down versions for free, but the real hope is that the free version will want folks to take the next step. “Free” is mostly transitory.
