I dunno about the code. But, they're definitely pushing their agenda here on Lemmy.
As far as I'm concerned, it's the only true negative aspect of Lemmy that I've noticed since I joined.
Everything here is pretty good. The users are mostly cool. Content is not high in quantity, yet, but it's decent quality.
Lemmy has one real, true problem, tankies. They're dishonest, they manipulate content, they brigade posts, they're a cancer. They have no home in legitimate link aggregation.
If it is true that they "built" Lemmy, it was only to get away from everyone who shunned them and forced them to find a safe place. And now they're mad that people who aren't deranged lunatics arrived in their safe place.
So far on Lemmy, whenever I see someone comment this, it's because they're mad Reddit got "toxic towards my free speech to stupid ass MAGA nonsense". Is that what you mean by Reddit being "toxified"?
