For context, I want to run a small personal gig (offering stuff on Patreon). Nothing too fancy.

In order to do that, I would need to use the Adobe suite, Windows, some audio and video effects, all requiring a commercial license.

In theory, I start to make money. How would Microsoft and Adobe know that I don't pay for their software?

If I use some audio effects, how would their owners even be able to tell / find my work? We're talking about basic sound effect, like rain, door knocks etc.

I've always been confused by this
