Indeed. Just an extension of FB as far as I’m concerned. I have no desire to share my location/likes/dislikes and everything else with them thank you.
I’ve used WhatsApp as my core messaging platform since 2009 and never ever associated it with being part of Facebook. I think they bought it recently so those of us that use it, well 99% of Europe, had no choice who decided to buy it. If I didn’t use it, I wouldn’t get social or work related messages as everybody uses it that I know. I only use iMessage with some immediate family.
