'Everyone' is treated as singular (aside from 'everyone are' sounding completely wrong).
replyDrop the "every" part and you can see the word that needs to be agreed with.
reply "One is supposed to do such and such."
"Everyone is supposed to do such and such."
"They are supposed to do such and such."
"People are supposed to do such and such."
"Someone is supposed to do such and such."
Part of the confusion may be that "everyone" is a single word while the example sentence in the Wikipedia article has a non-compound example.
"Every glass is ..."
I think that's the case for all the "every <noun>". "Every human is a person", for example. This would make sense, to put it in programming terms - the verb applies to an element in an array of people, not the array itself (which would be plural): for every single human, that human is a person.
replyConfidently incorrect.
replyNo, grammatically "everyone" is an indefinite pronoun. a single collective unit.
replyIs that a British thing? Nobody in North America uses "everyone are"

reply> The words everybody and everyone are pronouns that describe a group of people, but grammatically they are singular. The last part of each word is a singular noun: body and one.
