I uninstalled WhatsApp 3 days back (deleted 3 somewhat largish groups of 15, 43 and ~34 - they all agreed to move to Viber). At least 10-15 of my friends have already done the same (uninstalling part). Almost everyone is one Viber anyway and some are now on Telegram too. Now, I don't know how much such migrations will affect user-base (and I don't guess too much) but it can be noted that this is also the user-base that does online shopping, rates products and does a lot of things online, so this is certainly going to put a dent.
