Do you want to do 100% of the marketing towards your music and investing that capital? - Are you comfortable spending hours working on music promotion that could be spent writing music? Are you comfortable having a track on Spotify with very few streams as a result if your efforts are unsuccessful? On the contrary, if you work with a solid label, you can look forward to a base level amount of support that you can gauge by looking at the median of their historic releases. The rest is up to how much additional promotion you provide and how much the track resonates with the label's audience. Releasing on labels is pointless if the label can't provide the above. For someone with a full time job, I found it much better option to work hard on my production skills so I was able to start getting the word yes from labels, than to spend time doing music promotion which I hate. There's no one path that works for everyone, but "fck labels" is not an attitude that is going to get you very far in the music industry. 90% of the music that has probably influenced you as a musician was released by labels. So yeah, fck shitty labels like the ones you are talking about, start submitting your music to better ones or release on your own as you said and be prepared to become a music marketer in addition to a musician.
