No, why would that be the case? All these companies are terrible and there's so much that boycotting can do without isolating you from your social circles. Here in Brazil it was already weird to be telling people I don't have Instagram. Not having WhatsApp means you won't do a lot of stuff, including talking to your doctor.

I get the privacy concerns but social isolation is worse for you. Do what you can and don't stress that much about it.

The app is always lagging behind the web version too, it's just not worthy it.

Yeah, they keep complaining about manga piracy but have you heard of any website where you can buy and read them digitally? Because I would, for a fair price.
