I don’t want to get involved with any discussion related to the “politics” ( on Envato platform, we could argue elsewhere 
)
but seems like you could notice the irony now.
Depending on the servers, you may have different results if the server is not supported fully, in these cases, authors may not be tied up by providing support especially making sure the demo content works.
I had similar issues on the servers located in UK/France and Russia/China, there’re limitations to the hosting due to “security” if the theme or demo data doesn’t work related on this issue, you need to solve the problem on your own
