The population of Indonesia is 249 million.
The population of Germany is 81 million, and that of France 66 million.
So more people speak Bahasa Indonesia than they do German and French combined.
But only a small percentage of Indonesians speak Bahasa (or a variant of it) as a mother tongue – mostly ethnic groups in Riau and Sumatra, such as the Minang people. The mother tongue of most Indonesians is the language of the ethnic group and culture they were born into. Bahasa Indonesia was from early days a trade language used for communication across the archipelago. Only in recent history was it declared the official language of the country.
“Okay, okay, professor, this is boring. Get to the point.”
The point is that many Indonesians have a cavalier attitude towards the “proper” spelling of words in Bahasa. The important thing is getting the meaning across.
This attitude spills over into English, especially tourist English.
