Personal politics, what age do they live in? Gender neutral has been the norm for quite some time. Females are welcome to exist, both as users and as developers.
As a non-native speaker, I really have a lot of problems using a plural word as singular. When I read it, I always have to read twice to check whether one or more people are meant. I rather read and use “she/he” even with the additional typing.
“they” ist kein Pluralwort. “they” ist ein Pronomen der 3. Person Singular sowie der 3. Person Plural. Das ist genau so, wie “you” ein Pronomen der 2. Personal Singular und der 2. Person Plural ist.
