Hello. tumbler is included Fedora repo. But "TUMBLR." or "TUMBLR" is trademark. https://tsdr.uspto.gov/#caseNumber=85585708&caseType=SERIAL_NO&searchType=statusSearch https://tsdr.uspto.gov/#caseNumber=85541352&caseType=SERIAL_NO&searchType=statusSearch I think that this is trademark problem, It is non-free. I suggest that resolve trademark problem. Thanks.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
I feel this is something only legal can answer. Perhaps an email to fedora-legal?
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
A very similar bug 1404936 for perl-Data-Tumbler was closed NOTABUG. IANAL but I don't see why the same logic would not apply here.
Thanks Yaakov. Closing since we have a comment from Spot on that bug. "I agree. The likelyhood of confusion here is practically zero. Closing."
