I have a question. Why can't Whatsapp or Meta make a markdown INFO only website for small business owners (e.g. technicians, shopkeepers, handyman, etc) using their immense reach and clout. The method of using whatsapp groups to keep users updated of the latest updates is not scalable or open.

Because they much rather have those small businesses use a Facebook page for that purpose, which is the status quo in the West.

too big to deliver simple solutions? youre making way too much sense and this would die in committee or be replaced when someone new needs to justify themselves by launching a new product to supplant an existing one.
