Earlier this year they sent a representative to Brooklyn to resolve certain doctrinal issues with the governing body.
I don't see anything particularly unusual in this. I don't see why a group of long term JW/elders/anointed should not visit bethel and whilst they were there "resolve",in other words clear up, issues they were not absolutely clear on.
I certainly don't think disliking the shiny new tech savy org makes the older ones "apostates"either, in fact it's par for the course & what the org would be expecting in many ways.
Nothing unusual here imho.
