My understanding is that all JWs originally took the emblems. Then when numbers went over 144k "noo lite" showed not all were destined for heaven but the leftover surplus were now going to live on
earth. These surplus ones did not attend the memorial as it was only for the anointed.
As numbers of the anointed declined they decided to invite the surplus to come and respectfully observe them sipping and nibbling and try to bring as many onlookers as they could find willing to waste an evening.
The numbers of those who sip and nibble have now declined to such an extent the "respectful observers" have got nothing to observe, except possibly some mentally ill person taking the emblems disrespectfully.
It is a bit daft inviting people to a meeting to observe no-one taking the emblems.
Anyone like to make a prediction on what the noo lite might be?
