That's... a stretch. China has "reeducation" camps for dissidents and a Great Firewall; Singapore has opposition MPs and overzealous use of libel laws against critics. The two are not particularly alike.

I have heard and seen some stupid takes on Singapore, but this takes the cake.

In the 2020 general elections, the incumbent PAP had its worst showing ever, with ~60% of the votes. There are 5+ other opposition parties that Singaporeans can and do vote for in free and fair elections.

In the PRC, there are no meaningful elections whatsoever.

Yes, but Singapore has much stronger rule of law than China, which is why the city state doesn’t fall apart.
