People who aren't familiar with mainstream Catholicism might not understand that TLM is a pretty powerful cultural signifier; it's something close to a separatist movement within the church (in fact, it's the launch pad for an actual separatist movement, SSPX) and it's quite conservative. When you hear the pejorative "tradcath", these are the people they're talking about.
Naturally, the tiny but vocal minority of people who attended the TLM found Francis very activating. But it's important to know that those people are not broadly representative of the church as a whole. Most Catholics I know would barely offer a shrug if you told them (they certainly wouldn't already know) that Francis had restricted the TLM.
SSPX is in no way separatist, that is severely misinformed. If anything it is reformist, as they recognize the pope as their legitimate ruler and the local bishops as the legitimate local authorities. The claim is not that Rome has failed, it is that papal authority does not extend to the banishment of the Latin Mass, a position many regular clergy agree with.
