My ideals
Digital technologies enrich people’s lifes, with no (hidden) exploitation.
True ownership of things is a right of users, including the full control.
Lasting value is provided by physical products, with no planned obsolescence. The functionality can be studied, and altered by product’s owners based on owner’s needs. Or, by a person of their choice they delegate or hire to do so.
Real free market with freedom for anyone to participate, invent, create and extend existing solutions, with no arbitrary restrictions.
No privacy violations, that could be misused as ultimate power to massively abuse, oppress, exploit or take unfair advantage of others.
