The admin here takes a conservative stance on defederation. He doesn't do it unless there are lemm.ee rules violations or network abuse. I haven't looked at any explodingheads content, but if it does not violate any lemm.ee rules and presents no network abuse it will probably not get defederated.
I agree with lemm.ee's philosophy on defederation and that's one of the reasons this is my home instance. In general you can't call for defederation just because you don't agree with content. If it's blatantly offensive then I suppose that would be valid grounds, but I would hope that reason is used sparingly. I mean discussion that's offensive to you may not be offensive to me.
That's good they won't be adopting WEI, but if my bank or some other critical site decides to enforce a desktop browser with it, I'm still in the same boat. I did think of a way to avoid a WEI browser on my desktop if it comes to that. I can probably substitute a phone app for any critical services, but that's still a drag. I don't like phone apps much, I use a desktop browser for everything.
I think Google's destruction of the Internet is most simply a matter of influence. If Chrome didn't have the huge market share they wouldn't be able to pull off this kind of thing, open source or not. Unfortunately people have a herd mentality with everything on the internet so we allowed it to happen by doing what we always do.
