I have to agree. BitcoinFX’ assertion falls in the face of considerable evidence to the contrary to what is, after all, a very tenuous string match.
In addition to the contradictory evidence already identified by PrimeObsession and previous honest assessment :
1. The soubriquet “j0nn9” was in use in April 2014 by someone calling themselves “Jonny”, working in the crypto arena “Building MaidSafe on ArchLinux”, bylined “Gepostet vor 30th April 2014 von j0nn9”
2. The GAP donation address listed on gapcoin.org has seen activity in 2019.
3. The gapcoin.org website page for “Gapcoin’s highest found merits” carries the headline date “as of 2020 March 31”.
4. The DNS registration for gapcoin.org was renewed on 2020-04-30. The server hosting gapcoin.org is now located in Denmark, according to the DNS resolution, previously the DNS resolved to a German location.
5. The posts, code documentation and comments testify to someone for whom English is a second language. (No implications other than that, j0nn9’s English is a damn sight better than my basically non-existent German.)
6. “Jonny Frey” is not an unknown name in Germany - an example
novacula Occami

There are also other Frey in USA that are more likely to be him.
