We could change this by providing a commercial license (version) of MCreator. Users that would like to use MCreator for commercial purposes and would like to have more commercially and professionally oriented features would simply pay for the commercial license. Such license could include other services such as mod update server, more storage, no ads on the website, collaborative work support too.
MCreator, as is, would stay free, but we would offer a commercial version too.
We made this survey to find out how much interest there is for such version so we get some insight whether we should move things in the direction of option for the commercial version.
