Case 1) No money make. Therefor no worry have.
Case 2) Use BIS program as tool to earn Money: Therefor Is a Business: Therefor must have a Business License. Dotting "i"s and crossing "t"s of doing Business. Its on the web as an AV, so your income is reported by Youtube or whoever, as they report all their payments to your national the tax office, and employ lots of people just to do to this; so they can claim you as a business expense! So you have to tell your national tax man, any way. (dependent on what you can earn before having to declare for tax)
Case 3 Use BIS program as tool to earn more than 1000 Dollars or Euros a month: Therefore is a succesful Business: So time to speak to BIS about License, probably, give BIS a cut, let BIS approve content as it is influential on their products market, and maybe do some work for/with BIS. Happy Grin time. If you are paying for a license as a percentage or whatever license model BIS choose, then you want to declare any payments made to BIS as a business cost as it comes off your profit and you can only be taxed on profit! No sense in you paying the tax on money you did not earn!
