FUD #1: TRON has no product.
They do have a product. The source code has been released and is currently on GitHub.com being improved and updated frequently.
That's not a PRODUCT. Creating random repository filled with some commits does not magically produces anything really working.
FUD #2: Plagiarized Whitepaper
Recently, reports were written claiming that certain sections of the English translated version of the TRON whitepaper were plagiarized from the IPFS and Filecoin whitepaper without references made to them.
However, copying of code in the crypto world is common. Almost every coin has a section of their whitepaper copied from another coin, with reference provided to avoid plagiarism.
That is exact definition of plagiarism. It is not something really awful, right, but without any NEW conceptions (and its implementation) it is just copycat.
FUD #3: No one in China knows Peiwo, does not have the user-base it claims.
Another FUD rumor that gained traction recently was that Peiwo, the 10 million user company created by Justin Sun, does not really have the user base that it claims. Evidence for this claim was to “Google it” for yourself and see that there was no proof of such a large user base.
Nobody still cares. There are millions of 10 million user companies all around the world.
