I think it's just if you're empire building - and Zuck is insanely good at this, one of the best - then it'll never be optimal to charge vs. grow massively and then monetize the larger attention base.
Zuck is also in a trench warfare competition with other social media players, it's far from a monopoly. He's historically been more inclined to do things that were worse for growth, but better for users when they had more of a dominant position - but he can't do that anymore.
Somewhat relatedly Apple really missed an opportunity with iMessage. Had they timed it right they could have had a dominant cross platform chat. Instead they're going to be stuck with the modern equivalent of BBM while Zuck and Meta erase their only remaining stronghold in the US as iPhone users continue to move to WhatsApp.

Google also had the opportunity to do this. Around the same time iMessage launched, Google made Hangouts the default SMS app on Android with a similar capability to upgrade to Internet-based messaging when all parties to a conversation had it. Hangouts was cross-platform. Rumor has it carriers whined and Google caved.
I'm kind of glad Google doesn't have a dominant messaging service, but it's only true due to their own lack of commitment.
Whereas Whatsapp was simple - only phone numbers to sign up, only text and images, only mobile phones. That simplicity meant my parents could onboard smoothly and operate it without having to navigate a maze of UX. I literally saw Whatsapp winning in real time vs Hangouts and other alternatives.
I used Hangouts for a while and had a bunch of contacts on it when it was Android's default SMS app. Many of them were not particularly technical, including one of my parents whom I don't recall telling to use it. If you were using an Android phone, you were probably already logged in to a Google account. iPhone users had to work a little harder for it (install the app and remember the password to the Gmail account they probably already had).
I don't recall the UX on the mobile client having extra complexity over other messaging apps if I didn't go digging in the settings, but it's been a while.
Here in europe every club/association/group has a whatsapp group chat. For instance here since the official app provided by the government has a super clunky UX most people get information from primary school through a whatsapp group chat managed by the parent's representative who has exclusive access to teaching group.
As a counter to your question I've never used whatsapp and never saw a reason. What group chats? Are they groups of personal friends or mostly things you would 'follow' like a football club?
There's no way they actually earned $500M/year. Even if Whatsapp had 100 employees making $200k/year on average, that's $20M on salaries. Add an another very generous $80M on infra/admin etc costs and they'd have been making $400M profit. With that much profit achieved within such a short period, in the QE funny money era they could have IPO'd at $50-100 billion easily.
This would not be true most places outside of the USA and maybe Canada. In a few countries/regions it might be a different third-party messaging app.
Went to South Africa on vacation last year. United lost our luggage on the first leg of the trip, which then became South African Airways responsibility to sort out because they handled our final leg.
I communicated directly with the SAA baggage agent over WhatsApp. Then communicated over WhatsApp with the courier delivering our bags . Best customer service ever.
