> ...WhatsApp isn't free. I have to spend hundreds of dollars upfront to buy a phone... WhatsApp works reliably on a staggeringly broad list of devices. You can get a supported phone for, like, $20 and stick a $5-per-month prepaid SIM in it (many of these plans in low-income countries specifically come with WhatsApp allowances) and be connected.
Yea that’s not free
This is like arguing that free Wi-Fi isn't "free" because some people only use ethernet. If you don't already own a compatible device, you aren't their customer anyway.
