Thank you! Lemmy is a tremendous contribution to the wider Fediverse, and no amount of "thank yous" is ever enough for people like you writing free software and giving freely to the public domain.
I have been on Lemmy, and around the Fediverse on various accounts since ~2021, and a suggestion I have seen promoted countless times is for communities which federate across instances. e.g. posts to Linux@lemmy.ml will show on Linux@lemmy.world as long as lemmy.ml and lemmy.world federate with one another. If I remember correctly, each of you have previously opposed this idea for multiple reasons. If you do still oppose such a feature, will you please reiterate why you think this is the wrong direction for Lemmy? Also, have you considered adding a multi-community feature similar to Reddit's multi-reddit feature which allows end-users to combine multiple federated communities into a single page just for them?
Unfortunately, generics can vary wildly in efficacy & quality. As @Aradina pointed out, sometimes the encapsulation is different (e.g. extended release coating vs. standard release), but also the form of the drug can differ (e.g. capsule, tablet, softgel, chewable, etc), chemical by-products from different manufacturing techniques may be present in different amounts, and different manufacturing processes can also yield different chiral enantiomer ratios in the end product.
The "same" drug from different manufacturers may vary in effectiveness / side-effects, and brand-name drugs aren't always the best formulations for most patients.
