because they “care about environment 😉” the €99 charger (which is almost mandatory for a new user) is sold separately.
It's because they're required by law to offer it without a power supply. See Article 3a, section 10.
Apple's first-party power supply isn't "almost mandatory", and doesn't cost 99€. The 20W model shipped with the Macbook Neo in other markets costs 25€ on Apple's German store, and a generic 8€ power supply from Amazon will work. The power supply most people already have for their phone will usually also work.
