The problem is that some people are never happy. They don't want to pay for anything, they don't want to see ads. There was this crowdfunded magazine called "Linux Voice". No ads in it, but some people still kept moaning about the price which was about... £5. It's gone, now. There is also beginner-friendly DAW called MuLab. Full version costs €69 Eur, but for nothing you can have version limited to four channels only. It comes with no ads, no dodgy stuff (toolbars, spyware, shareware itp.) included in the installation file, but when I once recommended it, I was told that I shouldn't be doing it, because the author is extremely greedy ("How dare he limit the free version to four channels only!?").
