It may not be very funny, but the funny thing about WannaCrypt is that it is somewhat of a failure! Unless the authors are spectacularly stupid (not entirely impossible incidentally), they have no way to recover their ill-gotten gains. The pile of looted bitcoins they have acquired is fully visible, so any attempt to use those coins will almost certainly result in them being tracked down – they have attracted too much attention.
Which is another aspect of the WannCrypt malware – it has highlighted the vulnerability (MS17-010) and caused a huge vulnerability hunt. Which is causing those who wrote other malware (such as Adylkuzz) to gnash their teeth, because otherwise their malware would have quietly worked away in the background. The malware authors behind Adylkuzz have probably made more money than the WannaCrypt malware authors … and may well get away with their loot too.
Which is why other malware authors “wannacry” – the attention that WannaCrypt has gotten has ruined MS17-010 for them.
