Singapore libraries are really annoying for foreigners because they don’t let you use the WiFi.

Thailand at least gives you a 1 hour pass.

Not that anyone asked but my ranking of public libraries in Asia

1/ Taiwan

2/ HK

3/ Thailand

4/ Laos (private libraries are cute, but hot…)

4/ Vietnam (Bring your passport!)

5/ Singapore

I haven’t been to a library in Japan or S Korea. I tried working from a community center in Japan but I couldn’t figure how it works.

It's not limited to their libraries. All of their public facilities are like this. Even their public swimming pools (not allowed to use them if you are a visitor, their digital ticketing system requires the local equivalent of a SSN). The official excuse is that it's tax payer subsidized.

It's very much a classist country where you position in society is determined by your immigration status. Everything there is tiered based on whether you are a "citizen" (first class), permanent resident (second class), and you are in a permanent out group if you are not in the above two classes. And if you are a foreigner, whether you are a white "expat" or a Dubai -style indenture servant migrant worker. Valley tech bros are obsessed with that country but all that glitters is not gold.
