Harrop seems to be starting to orbit Prior more than McKinnon and Hayden, which is arguably a smarter move.
Harrop seemed genuinely pissed at McKinnon when Rhys tweeted his delight at Magdalene Burns having cancer, and I get the impression Harrop has backed away slightly from him.
Then Hayden comes with his own problems, Harrop is at some point going to be looking at joining a GP practice, and entering into a business relationship with GP's who tend to be pretty risk adverse. You could argue about which aspect of Hayden's character and history is worse, the history of violence and making thinly veiled threats on twitter, business's that have collapsed messily, or his reputation as a serial litigant (that last one in particular makes people nervous in the UK).
Prior seems to realise that the Trans community is fucking up with how it engages with people. The Forstater case and the reaction it got is causing the typical Troon to lose his shit on twitter. All anybody needs to do to respond to any any troon's tweet on the subject, is to post a picture of a smiling Gregor Murray and suggest they look into his history. Prior is trying to make a defense of the judgement that seems to be similar to Patreon's old 'Manifest observable behavior' bullshit, which ultimately neither side will buy into.
