One could look at the concept of the fediverse and relate it to the ideals of segregating higher powers (big businesses) and giving power to the working class (pay for labor). IE: the concept of dividing up Lemmy as a service into multiple-owned servers instead of a single monolith like Reddit. This tends to align with the ideology of Leftism (to be clear, the progressive class of beliefs, for anyone non-American) tend to be more inviting and inclusive to people. This makes for a good platform for trans people to feel welcomed.

This is not a factual answer, and I do not believe anyone here holds the authority to state a fact. It is only my personal observation.
