Did you even read what I have written? NEM Group told everyone that they are working closely with exchanges to ensure they have everything ready before the snapshot. If they have on influence in the Exchange listing they should just said nothing.
Did they sign any MOU for airdrop allocation and listing?
Do you check two lists on NEM website? One list for exchanges that support airdrop allocations. One for exchanges that support airdrop allocations and listings.
Binance is not in the list of listing support but they finish to distribute airdrop. They show they are preparing wallet for Deposit and withdrawal. Do you think they don't have a Symbol wallet when they already allocated airdrop?
It is a lie from them to delay allowance for deposit and withdrawal but they did not break anything if eventually they don't list Symbol on Binance.
You are a funny dude. All the balances you are seeing on your exchange account are just database entries and not actual wallet balances. Binance does not need an operational Symbol Wallet to allocate the Airdrop to your account. They just look at the trading data and XEM balances of each account and then add a database entry for your XYM balance.
So they are not sitting on their hands but are now actually implementing the Symbol Wallet into their System now which will take some more days. Only the NEM Group is telling lies here when they said they are working with exchanges upfront for the wallet integration.
