I wasn't downplaying the problem with widespread infrastructure being Huawei? The scenario you're describing is exactly what I was alluding to in my #1. Rather the comment I responded to seemed to just be uncritically beating the dead horse of "Huawei bad", when it's not really a big deal in the individual use context. And in fact rereading the original post, the original ISP-supplied gear was Huawei as well! Which I do agree that widespread usage of is a problem. But the author's replacing of a Huawei standlone ONT with a Huawei SFP ONT doesn't affect much there! And sure maybe it could have been great opportunity to harden up the author's infrastructure so that they could still have comms even if everyone else's went dark. Except that the OLT (other end of the link) is likely Huawei as well since ONTs aren't chosen in a vacuum.
