That's correct. The license agreement requires purchasing a commercial license per product if it reaches a certain revenue threshold. I believe this price should be feasible for a business, and this restriction is not unfair for regular programmers either. To clarify, the license needs to be renewed annually to continue receiving new versions from me. Additionally, I reserve the right to change the price in the future. However, license renewal is not a strict obligation. You can continue using the previous versions if you buy the license at least once.
The idea is to replace the donation model widespread in typical OSS projects with a formal obligation to purchase a license. I believe this approach more accurately expresses what the authors really want in exchange for their labor.
