Does it make sense to pay to use open source libraries like Awesomium?

Question

open source

There are a number of libraries, such as Awesomium, Juce. They are open source, but their use in commercial software is prohibited, or they are allowed but with certain restrictions, while the code is available to anyone. I'm wondering if these licenses have some kind of legal basis in the CIS and beyond, or are they just black letters on a white background?
Thanks

Answer 1

CIS, in your opinion, is it some kind of Papuan? Why doesn't copyright law apply here?
1. The owner of exclusive rights to intellectual property (work) has the right to independently establish the conditions under which he grants the right to use this performance. These formal conditions constitute a license.
2. The consumer has the right to refuse the conditions offered to him (under the license), which means refusal to use the work, or agree to these conditions and carry out the use. In case of agreement between the consumer and the copyright holder, the use agreement begins to operate, the terms of which are specified in the license.
3. Failure to fulfill any of the clauses of the contract by one of the parties may result in a lawsuit from the injured party.
4. The court will clearly explain the meaning of "black letters on a white background" to the dumb.

> There is a certain set of libraries, for example Awesomium, Juce
Are you deliberately choosing the most useless libraries?
Juce is generally UG, which is not necessary for nothing.
Awesomium is still so-and-so, but it seems that it is not prohibited for commercial software, but only for one where the profit is huge.
Or does the commercial version contain some additional features (which I don't know)?
And such a question: why do you need a browser engine at all? So I realized that they are practically not needed, and Awesomium has been gathering dust for a year now.
