If it weren't for the numerous YouTube videos of the Resistance sermons (+Williamson, Frs. Chazal and Hewko [the 'early' days], I'm not sure I would have seen the problems in the neo-SSPX; especially as a Novus Ordo convert.
I started recording sermons myself, coming from a photography background, to be put online. If you're interested, I run a YouTube channel with some content from +Williamson, +Faure, Frs. Voigt, Chazal, MacDonald, and Hewko (nothing past 2015) and the Avrille Dominicans. The channel is SoldierofChristtheKing (not sure if I can link to it here or not) Due to my current geographical placement, some priests are featured more than others on the channel.
Aside from traveling to record the sermons, Fr. Voigt allows me to upload the content he records himself. It's quite edifying to see the amount of work Fr. V. does to help us scattered sheep.
I used to upload Fr. Pfeiffer's sermons as well, but now I see his words are being used to cause division in the Resistance and support his own agenda/pride. I think the reason you see so many of Fr. Pfeiffer's (and Fr. Hewko's) content is the tactics used by Fr. P and Pablo to keep the media propaganda going. In my personal interactions with OLMC, I came to learn they want to have a 'tight grip' on the P.R. of the Resistance (at least how they want to see it) and will try to bully anyone who disagrees about how they are trying to run things. Even to the point of spreading mistrust and lies about fellow priests.
I have found some other YouTube channels that upload content from English speaking priests, if you're interested:
Maria Duce
Joy Steps
Saint Jude Thaddeus
pprzes01
deprecamur
Just my own two cents why we don't see content from other Resistance priests:
Seeing what can happen from being too public, as in the case of Fr. Pfeiffer, perhaps the other priests are acting out of humility of not wanting to have their sermons be put online? If this is the case, I understand it, but as a layman I would prefer to have access to Fr. Zendejas' amazing sermons, among other priests, as well.
