I just wonder what the SSPX (officially, or an individual priest locally) would advise their faithful to do in a hypothetical scenario:
A terrorist attack happens, and planes are grounded for 1 week; afterwards riots and other unrest cause the outage to last 2 weeks longer, for a total of 3 weeks.
A few places in the USA do not have a resident priest, but they do have a Resistance-affiliated chapel close by. Let's say these places have Mass for whatever reason (the priest is stranded there, or Bp. Zendejas does a lot of driving, etc.) These same places ALL have an Indult or FSSP option.
The Internet is still up and running, and so the SSPX is able to advise all its faithful on where they should attend Mass (if at all).
I honestly think the SSPX would advise people to go to the FSSP/Indult, or perhaps advise them to stay home and pray the Rosary, but I can't see them approving attendance at the Resistance-affiliated chapels.
The neo-SSPX fears the Resistance the most, because it represents the SSPX in the past -- and if the Faithful check it out for themselves, they might notice that A) they're not the evil bogeymen that SSPX.org and Angelus Press have made them out to be, B) the chapels are just like SSPX chapels were in the past, C) some things have changed in the SSPX recently, and not for the better.
Needless to say, the SSPX taking such a stand is ridiculous, but reality is reality.
