He has convinced himself that he cannot be an activist if he isn't a "professional" one, by which he means that his activism work generates enough income for him --and his family, and Tibor-- to live comfortably.
He received €82K in revenue. We don't know exactly how that breaks down, but there are three possible streams for Ipsilon Media - YT ad revenue, Google ad revenue and Patreon. Book sales and merchandise I believe are funneled through JLE Publishing in the UK. That was £10K last I looked. So essentially, he has well over €90K of revenue he received through selling books and merchandise, ad revenue Google and YT sent him, and Patreon. And he told Andrew Gold and in other instances that Patreon was by far the largest income source.
If he wants to hire Tibor and Dijana, fine - nothing illegal about that. But he has €90K to work with, so figure it the fuck out. Hint: The more employees you have and the more they are paid, the less you will be compensated as the owner. If he can't afford them, then sack them (well, he can't fire Dijana) or something else has got to drop. He's well compensated enough to figure out issues such as staffing, salaries and purchasing/replacing equipment. If he has to lay Tibor off, then he needs to go back to what he was doing before 2020 and edit the fucking videos himself.
To take his payroll and equipment issues to the public via Twitter is unprofessional and unheard of. If he's not pulling in enough, then figure out a way to market yourself or improve your branding instead of playing the victim card and initiating bullshit lawsuits. His content and services provided last year took a huge dive, so I don't know what he's complaining about with salary shortages. Might want to make a few internal changes, how about it, chief? Deal with it privately and be a man, not a whiney little bitch.
