No worries, your statement keeps its essence irregardless:
"Everyone is welcome in the #fediverse no matter the endpoint used, feel free to join in."
(No matter if #calckey , #pleroma , #soapbox , #misskey or any future derivate)
Usually you phrase your sentences in a way that makes misinterpreting hard.
Which is the proper choice.
