There's some really serious infighting between the two. TRS figures like Mike Enoch and Eric Striker had consistently mocked Jason's lexicon and online activism on their paywalled shows, comparing him to L. Ron Hubbard and mocking his concept White wellbeing as "White wellpeeing", althewhile refusing to refer to him by his online moniker and clarify who they were talking about, leaving their viewers unable to look into the ideas they were mocking. Jason mostly ignored this aside from mentioning it once or twice to illustrate their pettiness and dishonesty.
At some point, one of the figureheads in TRS allegedly asked Mark Collett, the host of Patriotic Weekly Review to not allow Jason to serve his role as a regular panel member when TRS or NJP representatives come on the show, and Mark obliged. Jason was mad at the TRS folkd for this and spoke about it on a number of shows, claiming he would be more than happy to talk to them if they allowed him to.
Recently, Jason did a number of videos and streams talking about the ineffective and counterproductive nature of PF's marches and vandalism and urged PF members to come to his movement, as well as telling the PF leadership to have some humility and resign in light of the Philly march. Jason claimed that whoever cosigned the Philly march idea is either a fed or a terrible leader.
On top of these already increased tensions between the two, there have been audio clips of TRS figures using Jason's lexicon and ideas like exclusively referring to antiwhites as antiwhites (most talking heads refer to antiwhites as communists, Democrats, globalists, etc.), whereas they previously claimed he was "jumping the shark". In the clip that Jason played, the hosts were acting like they had come up with this idea on their own.
I might be biased as a Jason shill, but my take on this situation is that the TRS hosts understandably see Jason as a bit odd, but decided to respond to his mere existence with complete and utter contempt, dishonestly adopting some of his ideas as ones they came up with and acting like he barely exists, gatekeeping and making it harder for people to find Jason's ideas of which they personally disapprove. Perhaps somebody who is more familiar with the TRS side of the situation can comment since I honestly haven't heard their side directly from them.
