That is not true. If the use of the tool provides "no value" to the company, then why on earth are they making the tool available. Yes, there is no money exchanging hands, but there is definitely some value.
Here's some value a company gets when someone uses a tool/piece of software without paying money (source: my company has a full feature free tool that competes with our paid offering, and often wins).
* awareness of the solution in the marketplace
* developer attention (way way easier to get a developer to try a free tool vs one that costs $0.01)
* bug finding (often in environments that would be hard to stand up for the company)
* user testing (related to bug finding, but often users will give feedback about feature direction)
* market share (if they are picking your free tool, they aren't paying for a competitor)
At my current job, we often leverage this (our GitHub issues repo and forum are main sources of our roadmap).
That's not to say that you should expect the same kind of service when you are a free user as when you are paying money. But attention is valuable too, esp of developers.
And it's not like if you pay money, a product company jumps to build whatever you ask for. Unless you pay a large amount compared to their current revenue and even then, if what you want conflicts with their long term vision, wise leaders won't.
