Thoughts on New community rule:
The expulsion of non english communities would be antithetical to the theme of the instance and would make the instance even more diluted with western media/culture, thus diversity of media/ideas/culture would be reduced.
It would be a huge disservice to many here who came to contribute for everyone to enjoy only for it to be gatekept by an english only restriction. Not to mention the potential zenophobic undertones that may be perceived as acceptable to such people.
Sure, non english speakers may not get to read your english post immediately but someone else in their region who learned english may see your post and will prompt them to share in their own language.
Perhaps it may be better to first discuss is great detail what problems this rule is trying to prevent and see if there are any feasible solutions before resorting to the worst case.
That isnt always the case. A single large machine will consume a lot of resources and will produce a large amount of waste which is often the reason why companies dont want to deal with it responsibly. Theres less thought into the infrastructure and is geared more towards profit which explains my why companies will always irresponsibly pollute with their byproducts. Think landfills, no matter how much money they throw to pass on the problems to another company, they will all cut corners. This has a far larger impact on the ecological system than a smaller machine.
On the other hand, a smaller self hosted machine allows for the person/local group to properly plan out the infrastructure to not only efficiently use resources but to also effectively process/handle byproducts.
