Catman is doing what is best for him. The more he can network with other content creators who have more subscribers than himself, he stands a good chance of increasing his subscriber base (which increases his income, obviously).
Back when he invited THP to TN and sent them to the public honeyholes here, many thought THP was just using him. Turns out Catman ended up using THEM as it indirectly tripled his subscriber base as the THP guys started featuring Catman in their videos driving up subscribers.
It's all about driving up likes, subscribes, comments to increase monetization if you want to try to make a living doing the tik/tok, FB, instragam, utube thing and feed yourself.
And its really, really tough to be successful I would imagine... Now anyone can buy the camera gear for less than $1000 and put it out there. So there are thousands doing it right now. How do you make your own channel unique and stand out? Killing giant bucks in urban backyards is certainly one way. At least Catman hunts ethically and does his best to follow the letter of the law.
But I don't think Catman was driven off this site (I may be wrong, some of you who have had actual face to face conversations with him might disagree), but rather he became exasperated because he made several enemies here by giving up and potentially ruining public spots that were good prior to the utube craze (certainly wasn't just his fault, lots of folks gave away too much information on this forum, other forums, and utube). Those enemies were going to call him out many times he got on here, and he is at the point where he really wasn't going to gain much from interacting on TNDeer any longer.
Again, this is just my opinion from watching his development/ interactions on this site. I don't watch him, THP etc any longer... just lost interest, and the THPs guys just became nails on the chalkboard irritating to me. Right now I've been watching 3 locals from the coast inshore fishing who have about 8,000 subscribers combined. They produce good content and include enough tips/ tricks/ suggestions to help me as a newbie inshore fisherman to learn from.
