I see no problem in anyone willing to toy with whatever he likes. I have a problem when huge efforts are invested by huge teams on huge projects which clearly have no purpose. I mean, if you have a lot of energy to use and give, and you want to clone something huge, clone one the proprietary tools that have no free/open source equivalent yet in your domain or one of the domains where there are the most serious lacks of FOSS; or clone a web app into a real desktop program; or reverse engineer a proper open driver for whatever device you have which request a proprietary OS, a proprietary driver or a manufacturer specific tool; rewrite a library which only exists in Python or C# into a C or C-compatible library so that every language on Earth can wrap it, etc. Don't go cloning something that is already free multiplatform software just for the purpose of cloning. We have never had so many people writing open-source programs, taking part in open-source projects, and yet it looks like the progress of open-source over proprietary (and its new form: services) is not what it was in the 90's and 2000's, it stalled, and it regresses in some areas. There has to be a problem somewhere.
