Mastodon communities currently defederate from instances of over a certain size (including .social) because of how hard it is to moderate large instances, beehaw isn't doing anything weird in this case.
This goes back to not voting in every election. Groups that invest (money, time, votes) on local races (city council, school board) have a greater variety to pick when one of these people goes on to higher office (state-level, county-level) and then goes on to federal office.
The primaries are already too late - it's all about the local races.
Realistically, whoever is the admin of the instance can decide to block another instance for any reason, or no reason at all. Admins of threadiverse sites are maintaining (and owning) these instances as a hobby. If they decide they don't want to look at content about penguins during their leisure time, they can just ... block them.
Since threadiverse is a bit less mature than the mastodon ecosystem, there aren't any "big" democratically owned and managed instances, so most people are stuck with benevolent dictator for life situations.
Edit: Also, if an admin doesn't want penguin content stored on their servers (which they pay for), it's a bit strange to say they must store content they don't like on what is essentially their personal machine.
For me the exciting part about bug farming isn't really their use as food (for humans or animals) but more their potential to eat "real" waste (like things that birds and mammals shouldn't eat) and then be turned into non-food items - like chondroitin or have other derivatives made out of their chitin.
Right now it's not very efficient but with some selective breeding (or faster, GMO mealworm gut bacteria) they could start working on the landfill issue. Their poop would have to be incinerated since it would concentrate flame retardants and other toxins, but we might be able to get something useful out of them.
edit: i have a box of mealworms that I wanted to try feeding just styrofoam to to see how many generations it would take to have mealworms that thrive (not just survive and turn to cannibalism) on the stuff, but i felt bad, now they eat kitchen waste and shredded paper.
I think the "magic" of bugs is that they can eat things that would be inedible or unhealthy for other omnivores (like pigs). If we can convert some of our food and paper waste into protein and chitin, it might be worth the investment.
if you ask generic customer what they feel about minor holiday X that retail stores make a huge deal about - if there aren't massive sales, most customers will be equally ambivalent.
there's nothing really to be "on board" about, it's an ignorable decor change. They don't even have music or large amounts of candy like in the winter holidays.
