I would be inclined to think people would do their research before complaining, but that would be expecting too much from people, I suppose.
All of these questions are answered all over the place.
They are in the testing phase now (phase 2 of 4), which could take days, something that was very well publicised, including a huge article on Coindesk.
Anyone with EOS coins on an exchange should currently leave them there, as there is no wallet yet. No one yet knows which will be the main chain, and untill they are certain everything works, a blockchain rollback is possible, hence they are in testing. Therefore, there is no wallet yet. There is also no block explorer yet.
EOS coins currently on exchanges are placeholders for what will be swapped to "real" EOS coins once people are free to move their holdings around. The exchanges I know of are taking care of any technical aspects of exchanging any placeholder coins into real coins for people with coins on their exchanges.
Whether various exchanges will honor any airdrops following (or happening during the launch) largely remains to be seen. Hopefully, most will. The more hell everyone gives the exchanges, the more likely they will be to honor any airdrops, hahahahahahaha. But do give them some time to sort through all the dust and make official announcements about airdrops before giving them any hell.
Additionally, anyone who pre-registered their ETH wallets and are holding their placeholder coins in an officially approved ETH wallet (as opposed to on an exchange), will gain access to any airdrops once the dust settles. Placeholder EOS coins in officially approved ETH wallets will then need to be claimed for real EOS coins once officially approved EOS wallets are up and running.
Remember, ERC-20 placeholder coins were just used for the ICO, and once real EOS coins are released into the wild, they will be their own animal, which means they will not be ERC-20 coins. The ERC-20 EOS coins are just placeholders for the balances people will use to claim real EOS coins once official EOS wallets are up and running.
Until people are 100% ABSOLUTELY CERTAIN they have determined what the main chain will be (as well as which wallets are officially on that chain), no one should attempt to move any coins around.
There will likely be a million scams, which is all the more reason to be 100% certain of what you are doing (from information distributed from official channels) before doing anything involving moving coins.
