There are all kinds of social media, its segmented by userbase, and culture/geography.
Telegram has 1B users (which is surprising to me, I thought it was an ex-Soviet thing), and there are entire geographic strongholds, such as Russia and China.
Russia and China still use iPhones and Windows, but entirely skipped out on Facebook and Whatsapp.
And for all the scorn it gets on HN, Facebook still works for some of my use cases: high school friends, low-contact relatives, obscure geography groups, the Philippines.
Your own link has Meta with 3 of the top 4 platforms. Can you really see any of the competitors overtaking them in even the medium term?

China doesn't use Google either, and while they might use Windows they're staying off Azure which is where Microsoft's main business is these days.
Yes there are countries which stay off Meta. But they are just as embedded in the workings of the world as any of the companies you mentioned, probably more so. Government decisions are made by people using a mix of Apple, Google and Microsoft hardware - but all of them are communicating over WhatsApp.
