Back before QOTO diverged too far from mastodon to be feasable most of our fixes were offered as PR to mastodon... surprise surprise Eugene usually rejected them for ideological reasons and here we are.
This isnt a case of "well its open-source"... no you have a highly opinionated guy running the scene who has made highly questionable and destructive decisions on various occasions and who has stifled good contributions to the codebase at every turn (and often gets called out)... So no the fault lies with Eugene here right fromt he getgo.
