5 years ago @gallioleo according to KiCad, we are using KEMET but we are using Samsung capacitors during production. So not much problems with that. We will still take your view into consideration. Thanks :)

From the ethical point of view are tantalum capacitors critical, cause tantalum is a conflict mineral - see link below. Another point are the cost of this capacitor. If the project doesn't need the high capacitance with small geometrical size, you should think about the phase out of these caps.
