This really is a completely nonsensical article.

The author is angry that his Spotify subscription becomes slightly more expensive, now running at EUR 12 per month instead of 11. So his solution is to instead rent a EUR 6.50 per month Hetzner server plus a storage space that starts at EUR 3.20 per month (next bigger tier is 10.90). Which means he is now paying at least EUR 9.70 per month for infrastructure, and he has invested a whole bunch of time, and he doesn't even have any actual music, because that would cost extra.
