I remind you that mastodon users can overcome the serious problem of not being able to view Lemmy communities in an orderly manner. The Raccoon for Friendica app, compatible with Mastodon, provides simplified viewing (viewing only topics) for all accounts of the Lemmy community, Friendica group or Gup.pe group type
In my opinion, this is not a contingent consequence, but the problem is a bit deeper: Mastodon staff knows well that helping Mastodon users to use groups better (for example by helping them to visualize them better) means helping competing projects like Friendica, Lemmy, Mbin, Piefed, gup.pe and even Peertube (which also works as a synolos between user (author) and group (channel). Helping the rest of the Fediverse means giving up the dominant leadership position that guarantees them subsidies, donations, visibility and, above all, the possibility to do whatever the fuck they want, imposing de facto standards.

PS: this is why I am a supporter of Friendica, Lemmy/Piefed, Wordpress, Mbin, Peertube and Bonfire: because virtuous competition brings diversity and diversity brings resilience
