Wondering if there's a consensus on who or which entities make up Trad Inc.?  What are your thoughts?

That could be.  I had the assumption the term was more specifically aimed at media types like Taylor Marshall, The Remnant, etc.  I don't look at either of those but was wondering who else was in that camp.

Anyone who enjoys relative popularity, makes good money, and isn't called too many serious names (anti-s3mite, conspiracy theorist, r4cist, etc.) AS a "Traditional Catholic".

Personally, I can tell the difference night-and-day. Let's put it this way: if you're 100% faithful to Tradition, telling the truth (cost what it may) etc. there is a huge glass ceiling over your head. And the glass ceiling is SO LOW, it's hard to even make a living.
The less you compromise, the smaller your audience, and the less acceptable you are to the "masses" or "mainstream", even among serious or conservative Catholics.

Just look at CathInfo. It has almost no competition as far as Traditional Catholic forums. It's been around 19 years. The forum is fast, well-moderated, etc. And does it have even 1/10th the reach of Taylor Marshall? Despite having dozens of times the information, analysis, and interesting content? I'm talking about the hundreds of members here, not myself.

Why wouldn't most of Taylor's audience prefer CathInfo? Because we are that list of -ists and -isms I mentioned earlier. They don't want the truth. They want conservative, or smells and bells -- but no farther. They're not interested in dying to (giving up) the world for Christ. They're not interested in putting Christ and His honor first to THAT degree. They don't want to lose any jobs or friends -- not even for the Truth or God's honor.

Let's step aside from criticizing any person or organization.

Just consider a hypothetical Traditional Catholic organization that could employ, say, 20 employees. Or even 10 employees. How would they afford this?
It's not a restaurant, and even most restaurants pay their low-end employees $15/hour now. So we're talking some serious cash.

You can't just start a Youtube channel, speak the truth, and get that kind of income. Youtube doesn't bring in what it once did. Unless you can reach the level of a Mr. Beast or CocoMelon. And that's not going to happen with ANY Catholic personality or organization.
Nor can you start a website and put up banner ads. Yeah right! CathInfo makes about 25 bucks a month now from advertising.

If you live off donations -- you're going to require a certain "breadth" of appeal to bring in enough money to pay 10 or 20 salaries. You would need to go beyond Traditional Catholics in the strict sense, whether classic SSPX/Resistance, independent, or Sedevacantist. There just isn't enough money sloshing around in the core of Tradition. Being faithful to Tradition makes you *poorer*, not richer. It's not like joining Fɾҽҽmαsσɳɾყ, where it turbo-charges your career. Quite the opposite. Eliminating countless (lucrative) career paths, PLUS having all the children God sends -- that's not a recipe for material wealth.

So you can't talk about X, Y, or Z. Otherwise say bye-bye to a huge chunk of your donors. As Steve Jalsevac complained about: as soon as they talked about more than "murdering babies is bad" (DUH!) they immediately start having issues with donors and donations.
No offense to the Pro-Life movement, but that's basic, baby stuff. How hard is it to convince people, even rabid atheists, that murdering babies in the womb is wrong? It certainly doesn't take the supernatural gift of Faith.
Talk about low-hanging fruit! It's like complaining about tranny men competing in girls sports, or Drag Queen Story Hour. Everyone's with you on that. Those opinions are downright popular. Perhaps the MSM tries to keep a lid on it, never show it, etc., but you're certainly in the majority, even if it's a silent majority.

You can either be a business (Trad Inc, with all the compromise that goes along with it) or be a niche forum/channel/blog/personality, speak only the truth -- and barely be able to support YOURSELF, much less any employees.
