Unfortunately, yes. I really wish the world would move away from Facebook, Instagram, and WhatsApp. Some countries heavily rely on WhatsApp and it's disgusting. Here in the UK a lot of companies now have a WhatsApp for customer service making it difficult or more hassle to get help.
It's easily the most used messaging app. My co-workers pester me to join WhatsApp and I've told them that if they want to get in touch with me they will have to either call or text me and I explained that since most of them have iPhones they could even Facetime or use iMessage but they didn't seem to understand what I was saying.
I straight up refuse to use any Facebook products. My boss tried getting us all on WhatsApp (I'm actually not the only one who doesn't use it) and I told her no I'm not using it. Thankfully it was just an idea she had and it wasn't something the higher ups told her to do. If it ever came to the point where it was mandatory work policy to use WhatsApp then I'd tell them I need a work phone. I am not installing any Facebook apps on my personal phone. It's not happening.
