I don't think everyone totally understands the EULA.
It's always been there, it's just become slightly stricter.
I believe that the EULA should absolutely be followed, but if you read through the EULA, it's not a huge deal. Large build teams and builder's are still allowed to take commisions, servers can still take donations, just not kits and perks.
If someone donates and in return the owner says "I want to give this person 60 diamonds." that's their own business.
Also if you do what Mineplex does, you can still sell kits and stuff, you just have to make it possible to access those kits and perks without JUST having to pay.
As long as there is a free alternative that isn't obsurd, then it is fine to have kits and perks.
Either way, if you build a strong community with good people, or invite a ton of friends on a private server, and you need money to pay for it. From what I've seen people are more than happy to help. Minecraft has one of the greatest - if not the greatest - gaming communities ever. So instead of asking "Should we follow the EULA" let's thank Mojang for caring about their community.
